Abstract:
Variability of Indian monsoon rainfall has been examined in relation to the convective activity of the equatorial trough over the Indian Ocean a~d the Pacific Qcean west of the International Date Line. It is found that the cyclogenesis (tropical cyclones) near the West Pacific equatorial trough is closely related to this variability through a see-saw in. convection between this ocean basin and north Indian Ocean, with period in the range 30-50 days. SST anomalies over north Indian Ocean and West Pacific Ocean can cause variability of the date of onset of monsoon and also the quantum of monsoon rainfall over India through the 30-50 day mode.

Abstract:
Abstract Year-to-year variability of surface air temperature (SAT) over central India is most pronounced in June. Climatologically over central India, SAT peaks in May, and the transition from the hot premonsoon to the cooler monsoon period takes place around 9 June, associated with the northeastward propagation of intraseasonal convective anomalies from the western equatorial Indian Ocean. Positive (negative) SAT anomalies during June correspond to a delayed (early) Indian summer monsoon onset and tend to occur during post–El Niño summers. On the interannual time scale, positive SAT anomalies of June over central India are associated with positive SST anomalies over both the equatorial eastern–central Pacific and Indian Oceans, representing El Niño effects in developing and decay years, respectively. Although El Niño peaks in winter, the correlations between winter El Niño and Indian SAT peak in the subsequent June, representing a post–El Niño summer capacitor effect associated with positive SST anomalies over the north Indian Ocean. These results have important implications for the prediction of Indian summer climate including both SAT and summer monsoon onset over central India.

Abstract:
India, leading to heavy rainfall. Such heavy rainfall result in floods for wider region of northern India, and, which, finally, causes loss of agriculture, human and animal’s life, outbreak of diseases/ epidemics, and thus affecting national economy. An attempt has therefore, been made to analyze the disastrous events that occurred in the summer monsoon months over different states in India for the period 1981-2000. The analyses included the raining event which were active, but, caused due to- or without the monsoonal-systems that were formed in north Indian Ocean. Results showed that West Bengal was the mostly affected state during monsoon season, where both, local as well as monsoonal systems were equally responsible for heavy rainfall/ flood events. The local atmospheric phenomenon affected highly to Uttar Pradesh, West Bengal, Gujarat, and Maharashtra, whereas for systems that were associated with the north Indian Ocean and Bay of Bengal, the states of West Bengal and Orissa were the mostly affected states. From the study, it may be concluded that all the heavy rainfall related disastrous weather events formed over different states in India was not only due to systems developed over Oceans, rather, local atmospheric phenomena had equally important contributor of similar affects, particularly for northern and western India.

Abstract:
Monsoon-Indian Ocean interaction is examined in detail using 5-dcgree square monthly mean data of ocean and atmosphere of two consecutive years of contrasting monsoon rainfall, 1972 and 1973. There was a major monsoon failure (drought) in 1972; in 1973 India had excess rainfall during the monsoon season. It is found that north Indian Ocean is colder than normal (negative SST anomaly) during the months prior to monsoon of 1972" During this –period upper tropospheric sub-tropical westerlies (monthly mean) intruded equatorwards over soJ1tlfAsia, farthest south over the Arabian Sea longitudes. The weak monsoon of June to Septemb~72 produced a warm SST anomaly over tropical Indian Ocean on account of decreased cooling of the ocean surface layer during the monsoon season due to decreased upwelling, particularly off the coasts of Somalia and Arabia, decreased wind mixing, decreased evaporation, and decreased clo1.lding. The positive SST anomaly of large spatial extent thus created persisted from October 1972 to May 19-73. The upper tropospheric circulation over south Asia during this period had equatorial easterlies (instead of westerlies) and increased strength of the sub-tropical westerly jet stream over north India. These results agree with observations and GCM simulations over Pacific Ocean with warm SST anomalies. Monsoon of 1973 was good and cold SST anomalies again appeared over north Indian Ocean from October 1973.

Abstract. The circulation in the North Indian Ocean (NIO henceforth) is highly seasonally variable. Periodically reversing monsoon winds (southwesterly during summer and northeasterly during winter) give rise to seasonally reversing current systems off the coast of Somalia and India. In addition to this annual monsoon cycle, the NIO circulation varies semiannually because of equatorial currents reversing four times each year. These descriptions are typical, but how does the NIO circulation behave during anomalous years, during an Indian Ocean dipole (IOD) for instance? Unfortunately, in situ observational data are rather sparse and reliance has to be placed on numerical models to understand this variability. In this paper, we estimate the surface current variability from a 12-year hindcast of the NIO for 1993–2004 using a 1/2° resolution circulation model that assimilates both altimetric sea surface height anomalies and sea surface temperature. Presented in this paper is an examination of surface currents in the NIO basin during the IOD. During the non-IOD period of 2000–2004, the typical equatorial circulation of the NIO reverses four times each year and transports water across the basin preventing a large sea surface temperature difference between the western and eastern NIO. Conversely, IOD years are noted for strong easterly and westerly wind outbursts along the equator. The impact of these outbursts on the NIO circulation is to reverse the direction of the currents – when compared to non-IOD years – during the summer for negative IOD events (1996 and 1998) and during the fall for positive IOD events (1994 and 1997). This reversal of current direction leads to large temperature differences between the western and eastern NIO.

Abstract:
Utilizing the marine meteorological data of the period 1961-81, the sea level pressure (SLP) and sea surface temperature (SST) distributions have been obtained on a 5° grid-mesh over the north Indian Ocean area bounded by 0°- 25°N, 50°- l00°E for each individual year. It has been found that the SLP and SST fields for the month of May provide predictive indications of subsequent summer monsoon rainfall over India. Significant negative correlations have been found between the mean SLPs of May over the latitudinal belts 5°-10°, 10°- 15°, 15°-20° and 20°-25°N of Arabian Sea and Bay of Bengal and all India rainfall departures of succeeding summer monsoon season. The mean SST gradient over the Arabian Sea between 7.5°- 17 .5°N during May has been found to have significant positive correlation with all India rainfall of subsequent monsoon. The study suggests that certain functions of SLP and SST of May over the north Indian Ocean can prove to be useful predictors for subsequent summer monsoon rainfall over India.

Abstract:
The relationship of genesis and intensity of cyclonic disturbances (CDs) over the north Indian Ocean with the Madden – Julian Oscillation (MJO) has been examined using 33 years (1975 - 2007) data of MJO index and best track of (CDs) developed by India Meteorological Department (IMD). The MJO index based on outgoing long wave radiation (OLR) and zonal wind in upper (200 hPa) and lower (850 hPa) troposphere (Wheeler and Hendon, 2004) has been used for this purpose. The MJO strongly modulates the genesis and intensity of CDs over the north Indian Ocean. However there are other factors contributing to cyclogenesis over the north Indian Ocean, as about 60% of cyclogenesis during monsoon and post-monsoon seasons are not significantly related with MJO. While the probability of cyclogenesis during monsoon season is higher with MJO in phase 4 and 5 (Maritime Continent), that during post-monsoon season is higher with MJO in phase 3 and 4 (east Indian Ocean and adjoining Maritime Continent). It indicates that while possibility of genesis during monsoon season is significantly suppressed with active MJO at phase 1, 7 and 8 (Africa, western Hemisphere and adjoining Pacific Ocean), there is no significant relationship between genesis and active MJO at phase 1, 7 and 8 during post-monsoon season. The anomalous cyclonic circulation at lower levels over central and north Bay of Bengal in association with MJO at phase 4 and 5 favours enhanced probability of cyclogenesis over the Bay of Bengal during monsoon season. The anomalous easterlies in association with MJO at phase 1 and development of anomalous ridge over south India in association with MJO at phase 7 and 8 which are weak monsoon features lead to suppressed cyclogenesis over north Indian Ocean during this season. The anomalous north-south trough in easterlies embedded with cyclonic circulation over the south west/west central Bay of Bengal in association with southerly surge over the region during active MJO in phase 3 and 4 most favourably influences the convection and enhances the probability of cyclogenesis over the north Indian Ocean during post-monsoon season. The genesis of CDs is more sensitive to phase than the amplitude while the intensification of CDs is more dependent on the amplitude of MJO. Comparing monsoon and post-monsoon seasons, the modulation of genesis, intensification and duration of CDs by the MJO is more during the monsoon season than the post-monsoon season.

Abstract:
The Indian Ocean Dipole (IOD), a climatic anomaly, results in sustained sea surface temperature (SST) variations between tropical western and eastern Indian Ocean temperatures. In this study, we studied the variations to inculcate the teleconnections between IOD and Indian summer monsoon rainfall (ISMR) distribution across the country for the period 1960-2020 for all the three phases of ISMR. We analyzed rainfall, SST and low-level wind circulation anomalies for the above mentioned time horizon. Positive IOD events noticeably resulted in increase in summer monsoon rainfall distribution across the country respectively while its negative counterpart led to decrease in rainfall except for the commencement phase of ISMR. The variations in SST, wind circulation and moisture movement processes across the Indian Ocean characterize significant changes in rainfall during the positive and negative phases of IOD especially during the recent decades (1991-2020). The recent time horizon also witnesses enhanced low-level equatorial jets (LEJ) across the equatorial Indian Ocean and the Arabian Sea during the positive IOD events as compared to the prior decades (1960-1990). The effect of moisture convergence zone is also analyzed which results in above rainfall conditions across northeastern and central India. Conversely, negative IOD events were found to subdue any such moisture movement mechanisms. Furthermore, and additional investigation to analyze the effect of IOD on the retreating/withdrawal monsoon across northeast India has been done and it has been observed that a stronger positive IOD is detrimental to the seasonal rainfall (May- September) over North East India (-0.7 one month lag correlation). Furthermore, the DMI index of April-May presented a clear indication of monsoon activity over the area during the withdrawal or retreating phase of the summer monsoon, i.e., during September.

Abstract:
The North Indian Ocean is a region with a high coastal population and a low-lying delta, making it a high-risk region for tropical cyclone impacts. A 30-year period from 1989–2018 has been used to examine the TC landfalling exposure in the North Indian Ocean and its changes by considering 30 years of IBTrACs data, ERA5 atmospheric data, and 20 years of TRMM and DAV data. A total of 185 TCs made landfall in the NIO during the 30-year period with the majority of the TCs making landfall during the pre- and post-monsoon seasons. Rainfall associated with landfalling TCs decreased in the last 10 years of analysis (2009–2018) compared to the first 10 years of available data from 1999–2008. During the monsoon, TC activity is relatively lower compared to the post-monsoon periods, even though higher accumulated TC-associated rainfall typically occurs during the monsoon period, particularly along the eastern coastlines of the Arabian Sea and the Bay of Bengal. The TC winds impact most of the Bay of Bengal coastline, including Sri Lanka. The spatial distribution of landfalling TCs changes with the season, with most of the landfalling activity occurring during the pre- and post-monsoon periods. Interestingly, more recent TC activity has shifted to the northeast India and Bangladesh coasts, suggesting that these regions may be more vulnerable to TC impacts in the future.

Abstract:
Analysis of the relationships between different phases of El Nio-Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), and Madden-Julian Oscillation (MJO) with tropical cyclone (TC) activity in the North Indian Ocean (NIO) is conducted. The relationships between ENSO and IOD are compared. Statistical analysis reveals a relationship exists. Each oscillation was examined to measure its statistical significance to TC activity in the NIO. The statistical examination was performed on the phases of each oscillation singularly and then all possible phase combinations of the three oscillations occurring concurrently. Analysis through combining concurrent occurrences of climatic oscillations indicates an increased statistical significance to TC activity in the NIO.

Pb and Pb isotopes in the ocean have varied on decadal to centennial time scales due to anthropogenic Pb inputs. Thus, tracing the temporal variation of Pb and Pb isotopes in the ocean provides information on the major sources of Pb and the transport of Pb from sources to the ocean surface and into the ocean interior. In this thesis study, first, a method was developed for the analysis of dissolved Pb and other trace elements in seawater using single batch nitrilotriacetate resin extraction and isotope dilution ICP-MS, which was applied in analyzing seawater Pb concentrations in the rest of the study. A -550 year history of the Pb and Pb isotopes in the deep North Atlantic Ocean is reconstructed using a deep-sea coral, showing the infiltration of anthropogenic Pb to deep sea. Comparing the results to the surface North Atlantic Ocean Pb record using a Transit Time Distribution model, the mean transit time of Pb is estimated to be -64 years. This is longer than the transit time estimate assuming simple advection from a source, showing the importance of advective-diffusive mixing in the transport of Pb to the ocean interior. The later part of the thesis investigates Pb in the Indian Ocean, where no useful Pb data have been previously reported. First, using annually-banded surface growing corals, I reconstruct variations of Pb and isotopes in the surface waters of the central and eastern Indian Oceans during the past half-century. Results of the study show the increase of Pb concentrations from the mid-1970s, and major sources of the Pb are discussed, including leaded gasoline and coal burning, based on their emission histories and Pb isotope signatures. Second, Pb concentration and isotope profiles are presented from the northern and western Indian Oceans. Higher Pb concentrations and lower Pb isotope ratios (206Pb/ 207Pb, 208Pb/207Pb) are found in the upper water column (by Jong-Mi Lee.

Abstract:
The first observations of deep-demersal scavenging fishes are presented from three regions of the world’s oceans with contrasting overlying productivity: the Mid-Atlantic Ridge (MAR) and Nazaré Canyon, Northeast Atlantic Ocean, and the Crozet Plateau, Southern Indian Ocean.  The MAR is the most significant topographic feature of the North Atlantic Ocean and is under the influence of a sub-polar front with increased productivity to the north.  Twenty-two taxa were photographed at bait; 14 at 42°N and 17 over two transects at 51 and 53°N respectively.  Decreases in biodiversity across the 51°N transect compared to the 42 and 53°N transects, support the hypothesis that 48°N - 52°N is a region of faunal change in demersal fish assemblages in the North Atlantic Ocean. The Nazaré Canyon is a large submarine canyon intersecting the Iberian continental margin which received high levels of organic matter from local upwelling and terrigenous sources. Nine fish species were photographed at the baited ROBIO lander at all depths within the canyon. It is hypothesised that the increased organic input positively influences benthic food supply within the canyon, supporting elevated populations of scavenging fauna.  The Crozet Plateau is situated in the southern reaches of the Indian Ocean, where the abyssal seafloor (ca. 4200 m) received differing levels of surface-derived organic enrichment.  Demersal ichthyofaunal biodiversity, abundance and biomass were sampled by a trawl at a eutrophic site (M5) and oligotrophic site (M6). Demersal fish species richness, abundance and biomass were greater at M5 compared to M6, and dominated by Macrouridae.  However, overall results were not significant, leading to the conclusion that the rattail fishes are transient between sites. Six species new to science were collected and are described herein (one Ophidiid, three Liparidae and two Zoarcidae), as well as several other rare specimens of Ophidiid and Zoarcid.

Full text
Abstract:
The applications of mid-Cretaceous (Aptian-Cenomanian) nannofossils in biostratigraphy and palaeoceanography have been advanced based on four specific studies from India, UK, the Atlantic and Pacific Oceans. A biostratigraphic study on outcrop samples from two new sections in the Cauvery Basin (SE India) has significantly improved stratigraphic resolution in the basin using the recent zonation schemes of Bown et al. (1998) and Burnett (1998). In addition to highlighting problems associated with a few marker species for the Cenomanian, the Albian/Cenomanian and Cenomanian/Turonian boundaries have been examined with respect to their nannofossil proxies. Qualitative comparisons of coeval assemblages from India with those from three other palaeogeographical settings (England, France and the Pacific) have confirmed the overall cosmopolitan nature of Albian nannofloras, in which provinces such as the Tethyan, Boreal and Austral cannot be clearly differentiated. A palaeoclimatic study of a short section in the Gault Clay (S. England) suggests a major warming event starting at the mid-/Late Albian boundary in the Weald of the Anglo-Paris Basin. The cold-water species, Repagulum parvidentatum, gives strong evidence for this warming event by showing a rapid decline in its percentage abundance, which precisely coincides with a light oxygen isotope peak and the influx of Tethyan ammonites. A sharp productivity rise based on the well-known fertility index, Zeugrhabdotus noeliae, is found to be concomitant with the warming event. A palaeoceanographic study of the Early Albian OAElb event in the western North Atlantic (Leg 171B), based on its nannofossil productivity record and geochemical data, supports the increased productivity model as a plausible mechanism for this anoxic event. A similar study on the Pacific Ocean (Leg 198, Shatsky Rise) shows a marked temporal variation in the abundance distribution of productivity- related taxa (e.g., Biscutum constans, Zeugrhabdotus noeliae) in relation to the OAEla (Early Aptian) and OAElb (Early Albian) events. Possible explanations for this variation have been proposed, in light of the heightened submarine volcanism in the Pacific during the mid-Cretaceous. Watznaueria is found to be the most abundant taxon in all mid-Cretaceous assemblages and its dominance is considered to be independent of preservation, indicating its broad palaeoecological tolerance rather than resistance to dissolution. On the basis of taxonomic observations, four new species have been erected: Calculites karaiensis, Loxolithus bicyclus, Manivitella fibrosa and Tranolithus simplex.

Abstract:
Abstract When the Dutch and English first entered the Indian Ocean, the primary goal of both nations was to gain a monopoly in the spice trade. To do this, they had to militarily push out the Portuguese and prevent the other from gaining a foothold. Ultimately, the VOC came out the big Winner taking control of the clove, nutmeg and mace trade of the Moluccas. It also took a considerable portion of the Indonesian pepper trade by force, but not all. With the loss of the Spice Islands, the British shifted their attention to India and its pepper, saltpetre, cotton and indigo. The VOC also turned its eyes to India, but with far less lasting impact. To gain their foothold in India the English and Dutch were faced with two significant challenges: they would need to gain the favour of the Mughals who now controlled most of North India and they would have to push back the Portuguese who were well entrenched along the west coast. The Mughals had left the Portuguese ports mostly alone, preferring to trade with them rather than fight.

Abstract:
Abstract This chapter discusses the reign of the Eastern Roman Empire as well as the state of the international trade during its golden era. It consists of thirteen subchapters which are about the Shift of Roman Power, the rule of Constantine, the drastic transition of world trade after the fall of the West Roman Empire, the exotic luxuries of Byzantium, the golden age of the Eastern Roman Empire under Justinian, Byzantine attitudes about trade. Trade in the Byzantine world was highly regulated by the state, the empire was essentially a huge trading organization. It continues with the subchapters, The Dollar of the Middle Ages, Trading with the Enemy, Aksum and Byzantium's Indian Ocean Connections, Christians Surrounded by Muslims, The Secret of Silk Escapes, which is about the mid-sixth century when most silk found its way to Europe through the Silk Routes across China and the northern steppes of Central Asia, the Justinian's Plague that spread along the great trade routes, emerging first in China and north-east India, travelling to Ethiopia, moving up the Nile to Alexandria and then east to Palestine and across the entire Mediterranean region, and lastly, The End of the Red Sea Portal. Some 1000 years of Greek and Roman rule over Egypt had ended and with it the Red Sea link of Europe with the Asian spice trade.

Abstract:
Multiple scale climate variability in Asia of temperate and high latitudes, Pacific, Indian and South Oceans, their features and linkages are studied by using statistical analyses of monthly mean time series of Hadley, Reynolds SST, surface net heat flux (Q), atmospheric pressure (SLP), air temperature (SAT) from NCEP NCAR reanalyses (1948-2015). Three multidecadal climatic regimes were revealed for the whole area studied by using cluster analyses via Principal Components of differences between values of Q, SLP, SAT in tropical and extratropical regions of the Asian Pacific, Indian and Southern Oceans. The climate regime change in 70s of the 20th century in this area is confirmed by this method. It is also found that the climate regime is significantly changed at the end of the 20th century in both same area and World Ocean. The characteristic features of recent climate regime after 1996-1998 are SLP increase in the central extratropic area of Indian Ocean, North and South Pacific being prevailing in boreal winter. It is accompanying SLP increase and precipitation decrease in South Siberia and Mongolia prevailing in boreal summer. Inversed SLP and precipitation anomaly associated with increase of cyclone activity and extreme events in the land-ocean marginal zones including Southern Ocean, eastern Arctic, eastern Indian, western and eastern Pacific margins. It is known that low frequency PDO phase is also changed at the same time.

Abstract:
Winter climatic anomalies of various time scales in the Japan, Okhotsk seas and Baikal Lake Basin are revealed and compared with anomalies in the Pacific, Indian and Arctic oceans. Time series of ice extent in the Japan and Okhotsk seas, ice thickness and seasonal duration of the ice cover in the Baykal Lake, as well as Hadley SST, surface heat fluxes, wind velocity, atmospheric pressure fields (SLP) and different climatic indices are analyzed. The decadal climate anomalies in the Japan and Okhotsk seas in mid winter, as compared to the Northeast Pacific and South Siberia regions, could have a reversed phase. Alternating cold/warm decadal anomalies in different longitude zones of the North Asian Pacific are accompanied by alternating meridional wind and SLP anomalies at temperate latitudes. Alternating zones of inversed anomalies in temperate latitudes of the Asian Pacific are related to teleconnections with anomalies in both Arctic and Indo-Pacific oceans. Negative SSTA in eastern/central tropical-equatorial Pacific and positive SSTA in El Nino area accompanies rise of northern wind and ice extent in the Okhotsk/Japan Seas in mid-winter. The best predictors of the high cold anomaly in February in the western subarctic Pacific and marginal seas are reduction of the SST and net heat flux from the atmosphere to the ocean in north-eastern and central North Pacific during warm period of a previous year. At the multidecadal time scale the warming/cooling in the Northeast Pacific accompany winter warming/cooling in the Baykal Lake area during all period of observation. At interdecadal time scales the significant link of winter climate oscillations in South Siberia (Baikal Lake Basin) is found with SSTA oscillations in the equatorial region of the Indian Ocean and certain areas of the Pacific Ocean. The linkages of anomalies in the Baikal Lake Basin, Okhotsk, Japan Seas with regional anomalies in some key areas of the Pacific and Indian Oceans, related to the atmospheric centers of action are more stable than that with climatic indices. After climate regime shift in late 70s warm decadal anomaly in both Lake Baykal Basin and Indian Ocean in boreal winter accompany high positive anomaly of the Arctic Oscillation. Scenarios of extreme anomalies in the Baikal Lake Basin and Subarctic Pacific marginal area are also presented.

Abstract:
Ocean energy developments are appearing around the world including Scotland, Ireland, Wales, England, Australia, New Zealand, Japan, Korea, Norway, France Portugal, Spain, India, the United States, Canada and others. North America’s first tidal energy demonstration facility is in the Minas Passage of the Bay of Fundy, near Parrsboro, Nova Scotia, Canada. The Fundy Ocean Research Center for Energy (FORCE) is a non-profit institute that owns and operates the facility that offers developers, regulators, scientists and academics the opportunity to study the performance and interaction of instream tidal energy converters (usually referred to as TISECs but called “turbines” in this paper.) with one of the world’s most aggressive tidal regimes. FORCE provides a shared observation facility, submarine cables, grid connection, and environmental monitoring at its pre-approved test site. The site is well suited to testing, with water depths up to 45 meters at low tide, a sediment -free bedrock sea floor, straight flowing currents, and water speeds up to 5 meters per second (approximately 10 knots). FORCE will install 10.896km of double armored, 34.5kV submarine cable — one for each of its four berths. Electricity from the berths will be conditioned at FORCE’s own substation and delivered to the Provincial power grid by a 10 km overhead transmission line. There are four berth holders at present: Alstom Hydro Canada using Clean Current Power Systems Technology (Canada); Minas Basin Pulp and Power Co. Ltd. with technology partner Marine Current Turbines (UK); Nova Scotia Power Inc. with technology partner OpenHydro (Ireland) and Atlantis Resources Corporation, in partnership with Lockheed Martin and Irving Shipbuilding. In November 2009, NSPI with technology partner OpenHydro deployed the first commercial scale turbine at the FORCE site. The 1MW rated turbine was secured by a 400-tonne subsea gravity base fabricated in Nova Scotia. The intent of this paper is to provide an overview of FORCE to the international marine energy community during OMAE 2011 taking place in Rotterdam, Netherlands.

Abstract:
With this script, the Meridional Overturning Circulation (MOC) can be computed from NEMO ocean-model output for the whole globe or the Atlantic (AMOC), Indic (IMOC) and Pacific (PMOC) subbasins. The MOC is computable in z- and sigma coordinates. Moreover, for nested configurations, it is possible to combine data from both host and nest grids. Finally, it is possible to take into account of that the ORCA model grid is curvilinear north of 20°N: it is possible to compute the northward velocity component from the velocity field in x- and y- directions and to sum up the meridional flux over latitudional bands instead of in x-direction. When both steps are applied, the resulting MOC shows however strong variability in meridional direction. It needs to be clarified, whether this is realistic or not. The software is provided in the form of the jupyter notebook "MOC.ipynb" which includes more informations on the possibilites of the computations and an extensive appendix section with comparisons to computations with cdftools, as well as with details on the computation of the MOC including nest data and taking the curvilinearity of the grid into account. Necessary python modules are listed at the beginning of the document.
