Spirulina platensis merupakan mikroalga hijau-kebiruan dalam kelas Cyanophyceae yang mengandung klorofil-a dan fikobiliprotein. Faktor lingkungan yang dapat mempengaruhi pertumbuhan dan pigmen Spirulina platensis salah satunya yaitu salinitas. Penelitian ini bertujuan untuk mengetahui pertumbuhan dan kandungan pigmen mikroalga Spirulina platensis pada salinitas yang berbeda. Metode penelitian yang digunakan adalah eksperimental laboratoris dengan menggunakan Rancangan Acak Lengkap. Hasil penelitian menunjukkan kepadatan mikroalga tertinggi pada (salinitas 15 ppt) sebesar 211.875±1994 unit/mL dan terendah pada salinitas 25 sebesar 141.539±5872 unit/mL. Laju pertumbuhan tertinggi didapat pada salinitas 20 ppt sebesar 0,327±0,019 unit/hari dan terendah pada salinitas 25 ppt sebesar 0,246±0,012 unit/hari. Kandungan klorofil-a berkisar antara 10,622±1,322 µg/mLpada salinitas 30 ppt dan 8,176±2,426 µg/mL pada salinitas 15 ppt. Kandungan fikosianin berkisar antara 0,105 ± 0,041 mg/mL (salinitas 20 ppt) sampai 0,058 ± 0,005 mg/mL (salinitas 30 ppt). Allofikosianin berkisar antara 0,069±0,010 mg/mL pada salinitas 20 ppt sampai 0,042±0,007 mg/mL pada salinitas 30 ppt. Kisaran fikoeritrin antara 0,384±0,159 mg/mL pada salinitas 20 ppt sampai 0,239±0,014 mg/mL pada salinitas 30 ppt. Berdasarkan hasil penelitian disimpulkan bahwa salinitas memiliki pengaruh signifikan terhadap pertumbuhan dan laju pertumbuhan, namun tidak pada kandungan pigmen mikroalga Spirulina platensis. Kandungan klorofil a dan fikobiliprotein yang terdiri dari fikosianin, allofikosianin dan fikoeritrin, tidak menunjukkan perbedaan yang signifikan pada salinitas yang berbeda. Spirulina platensis is a blue-green microalga in the Cyanophyceae class that contains chlorophyll-a and phycobiliprotein. One of the environmental factors affecting the growth and pigment of Spirulina platensis is salinity. This study aims to determine the growth and pigment content of Spirulina platensis at different level of salinity. The research was carried out from March till April 2020 at the Marine Biology Laboratory and Marine Chemistry Laboratory, Building E, Faculty of Fisheries and Marine Sciences, Diponegoro University, Semarang. The research method used was a laboratory experiment using a completely randomized design. The results showed that the highest microalgae density achieved at salinity 15 ppt as 211.875±1994 units/mL, meanwhile the lowest was gained at salinity 25 ppt at 141.539 ± 5872 units/mL. The highest growth rate was obtained at 0.327 ± 0.019 unit/day at salinity 20 ppt, and the lowest was achived at 0.246 ± 0.012 unit/day at salinity 25 ppt. The chlorophyll content ranged from 10.622 ± 1.322 µg/mL at salinity 30 ppt and 8.176 ± 2.426 µg/mL at salinity 15 ppt. The phycocyanin content ranged from 0.105 ± 0.041 mg/mL at salinity 20 ppt to 0.058 ± 0.005 mg/mL at salinity 30 ppt. Allophycocyanin ranged from 0.069 ± 0.010 mg/mL at salinity 20 ppt to 0.042 ± 0.007 mg/mL at salinity 30 ppt, and phycoerythrin ranged from 0.384 ± 0.159 mg/mL at salinity 20 ppt to 0.239 ± 0.014 mg/mL at salinity 30 ppt. The results suggested that salinity had a significant effect (p<0.05) on density biomass and growth rate of Spirulina platensis microalgae, but did not influence on pigment concentration. Measurements of chlorophyll-a and phycobiliprotein content, including phycocyanin, allophycocyanin, and phycoerythrin indicated that salinity did not affect the pigment concentration of microalgae Spirulina platensis.

Penelitian ini bertujuan untuk mendeskripsikan sebaran suhu dan salinitas di Teluk Manado, Sulawesi Utara. Pengukuran suhu dan salinitas secara vertikal dilakukan di delapan tempat di teluk. Profil vertikal suhu dan salinitas memperlihatkan keberadaan pelapisan kolom air. Secara horizontal, kontur suhu dan salinitas di permukaan memiliki dua “kolam” massa air, yakni kolam yang bersuhu tinggi tapi bersalinitas rendah di bagian timur teluk dan kolam yang bersuhu rendah tapi bersalinitas tinggi di bagian barat teluk. Pada lapisan dalam, kontur suhu dan salinitas cenderung sejajar dengan garis pantai bagian timur. Kata kunci: suhu, salinitas, air sungai, Teluk Manado. The objective of this research is to describe temperature and salinity distribution in Manado Bay, North Sulawesi. The vertical measurements of temperature and salinity were done at eight locations in the bay. The vertical profiles of temperature and salinity shows the existence of water column stratification. Horizontally, temperature and salinity contours of the surface layer have two pools, i.e. a pool of high temperature but low salinity in the eastern part of the bay and a pool of low temperature but high salinity in the western part of bay. In a deeper layer, the contours of temperature and salinity tend to be parallel to eastern coastline. Keywords: temperature, salinity, river discharge, Manado Bay.

La tomate est l’un des légumes les plus consommés au monde et au Bénin. Il est largement établi que la salinité agit négativement sur la germination et la croissance et modifie considérablement la concentration des composés bioactives des légumes. Au Bénin, la tomate est cultivée partiellement sur les terres cultivables des régions côtières où la salinité du sol et de l’eau d’irrigation est une réalité. Cette étude visait à évaluer l’effet de la salinité sur la floraison, la fructification et la composition nutritionnelle des fruits de tomate du cultivar local Akikon. Les plantes de trois semaines ont été arrosées jusqu’à la maturité des fruits avec diverses concentrations de NaCl de 0, 30, 60 et 120 mM. La date d’apparition des premières fleurs, la date de maturation des fruits ainsi que les teneurs en protéines des fruits n’ont pas été significativement affectées par la salinité alors que le nombre de fruits par plante, le poids des fruits, les teneurs en sucres solubles totaux et en sucres réducteurs subissent une réduction significative sous l’effet du NaCl. Par contre, les teneurs en lycopène, en vitamines B6, B12 et C ont connu une augmentation significative avec l’augmentation de la concentration de NaCl. La salinité a donc réduit la production de tomate et amélioré la qualité nutritionnelle des fruits en augmentant notamment ses teneurs en vitamines et en lycopène.Mots clés: Salinité, teneur en nutriments, sucres, lycopène, vitamines. English title:Effect of salt stress on flowering, fructification and fruit nutritional quality of Benin local tomato (Lycopersicon esculentum Mill.) cultivar AkikonTomato (Lycopersicon esculentum) is one of the most important consumable vegetable in the world and in Benin. It is widely established that salinity acts negatively on germination and growth and considerably modifies the concentration of bioactive compounds in vegetables. In Benin, tomato is partially cultivated on arable lands in coastal regions where soil and irrigation water salinity is a reality. This study investigated the impact of salinity on flowering, fructification, and fruit nutrient contents of a local cultivar of tomato Akikon. Three weeks old plants were irrigated with four NaCl concentrations: 0; 30; 60 and 120 mM NaCl till fruit ripening. The date of first flower appearance, the date of fruit ripening and fruit protein content were not affected by salinity; whereas fruit number, fruit fresh mass, fruit soluble sugars and reducing sugars contents were significantly decreased by increasing salinity. Moreover, lycopen and vitamins B6, B12 and C contents increased significantly when salinity concentration increased. Thus, salinity reduced tomato productivity but improved fruit nutritional quality by mainly increasing vitamins and lycopen contents.Keywords: Salinity, nutrients content, lycopen, sugars, vitamins.

Among abiotic stresses, high salinity stress is the most severe environmental stress. High salinity exerts its negative impact mainly by disrupting the ionic and osmotic equilibrium of the cell. In saline soils, high levels of sodium ions lead to plant growth inhibition and even death. Salt tolerance in plants is a multifarious phenomenon involving a variety of changes at molecular, organelle, cellular, tissue as well as whole plant level. In addition, salt tolerant plants show a range of adaptations not only in morphological or structural features but also in metabolic and physiological processes that enable them to survive under extreme saline environments. The main objectives of my dissertation were understanding the main physiological and biomolecular features of plant responses to salinity in different genotypes of horticultural crops that are belonging to different families Solanaceae (tomato) and Cucurbitaceae (melon) and Brassicaceae (cabbage and radish). Several aspects of crop responses to salinity have been addressed with the final aim of combining elements of functional stress response in plants by using several ways for the assessment of plant stress perception that ranging from destructive measurements (eg. leaf area, relative growth rate, leaf area index, and total plant fresh and dry weight), to physiological determinations (eg. stomatal conductance, leaf gas exchanges, water use efficiency, and leaf water relation), to the determination of metabolite accumulation in plant tissue (eg. Proline and protein) as well as evaluation the role of enzymatic antioxidant capacity assay in scavenging reactive oxygen species that have been generated under salinized condition, and finally assessing the gene induction and up-down regulation upon salinization (eg. SOS pathway).

Salinity represents the major environmental threat to arable land in Western Australia and many other parts of the world. This study was designed to establish criteria for a practical remote sensing system using the visible, reflected and shortwave infrared for the early detection and mapping of salinity. The results are principally from a group of study sites on the CSIROs Yalanbee Experiment Station, and from other significant sites during the agricultural cycles of 1985-7.Analysis of imagery from the Geoscan Multispectral Airborne Scanner showed that best discrimination between study sites affected by salinity, and those not affected, was provided by bands 3 (650-700 nm), 4 (830-870nm) and band 6 (1980-2080nm). The maximum discrimination occurred in a September 1986 flight (spring-flush). Although excellent discrimination was also evident in August and November in 1985, this could not be reproduced in November 1986. The visible and reflected infrared bands 3 and 4 featured prominently, but the significance of the short wave infrared bands was evident especially when vegetative ground cover became a less dominant factor.Field spectra collected over the same period with the Geoscan Portable Field Spectroradiometer (PFS) supported the aircraft data to a certain extent. Detailed analysis of the fine non-correlated structure of narrow constructed bands, from PFS data, indicated that improved discrimination between sites could be provided over a wider time window extending into the summer and autumn. This is when weather-related conditions, i.e. cloud, soil moisture and sun angle, are more conducive to extensive surveys.The importance of at least one narrow band centred near 1985 nm was determined. Laboratory spectra of bare soil from sites measured on an Hitachi Spectrophotometer also provided the importance of the shortwave region adjacent to the 1900 nm water absorption.The study evaluated the spatial and spectral characteristics of existing satellite systems such as Thematic Mapper and the Multispectral Scanner on the Landsat series and determined that a spatial resolution of about 20-30 metres was most appropriate for detection of salinity at a scale whereby management could be implemented.Ground electromagnetic techniques were evaluated during the study and the EM-38 Ground Conductivity Unit proved valuable for characterizing salinity status of the sites. The Lowtran Computer Code was used to model atmospheric attenuation and results indicated that the positioning of a narrow shortwave infrared waveband, centred at 1985 nm, is possible.

L’oceanografia per satèl•lit ha esdevingut una integració consolidada de les tècniques convencionals de monitorització in situ dels oceans. Un coneixement precís dels processos oceanogràfics i de la seva interacció és fonamental per tal d’entendre el sistema climàtic. En aquest context, els camps de salinitat mesurats regularment constituiran directament una ajuda per a la caracterització de les variacions de la circulació oceànica global. La salinitat s’utilitza en models oceanogràfics predictius, pero a hores d’ara no és possible mesurar-la directament i de forma global. La missió Soil Moisture and Ocean Salinity (SMOS) (en català, humitat del sòl i salinitat de l’oceà) de l’Agència Espacial Europea pretén omplir aquest buit mitjançant la implementació d’un satèl•lit capaç de proveir aquesta informació sinòpticament i regular. Un nou instrument, el Microwave Imaging Radiometer by Aperture Synthesis (MIRAS) (en català, radiòmetre d’observació per microones per síntesi d’obertura), ha estat desenvolupat per tal d’observar la salinitat de la superfície del mar (SSS) als oceans a través de l’adquisició d’imatges de la radiació de microones emesa al voltant de la freqüència de 1.4 GHz (banda L). SMOS portarà el primer radiòmetre orbital, d’òrbita polar, interferomètric 2D i es llençarà a principis de 2009. Així com a qualsevol altra estimació de paràmetres geofísics per teledetecció, la recuperació de la salinitat és un problema invers que implica la minimització d’una funció de cost. Per tal d’assegurar una estimació fiable d’aquesta variable, la resta de paràmetres que afecten a la temperatura de brillantor mesurada s’ha de tenir en compte, filtrar o quantificar. El producte recuperat seran doncs els mapes de salinitat per a cada passada del satèl•lit sobre la Terra. El requeriment de precisió proposat per a la missió és de 0.1 ‰ després de fer el promig en finestres espaciotemporals de 10 dies i de 20x20. En aquesta tesi de doctorat, diversos estudis s’han dut a terme per a la determinació del balanç d’error de la salinitat de l’oceà en el marc de la missió SMOS. Les motivacions de la missió, les condicions de mesura i els conceptes bàsics de radiometria per microones es descriuen conjuntament amb les principals característiques de la recuperació de la salinitat. Els aspectes de la recuperació de la salinitat que tenen una influència crítica en el procés d’inversió són: • El biaix depenent de l’escena en les mesures simulades, • La sensibilitat radiomètrica (soroll termal) i la precisió radiomètrica, • La definició de la modelització directa banda L • Dades auxiliars, temperatura de la superfície del mar (SST) i velocitat del vent, incerteses, • Restriccions en la funció de cost, particularment en el terme de salinitat, i • Promig espacio-temporal adequat. Un concepte emergeix directament de l’enunciat del problema de recuperació de la salinitat: diferents ajustos de l’algoritme de minimització donen resultats diferents i això s’ha de tenir en compte. Basant-se en aquesta consideració, la determinació del balanç d’error s’ha aproximat progressivament tot avaluant l’extensió de l’impacte de les diferents variables, així com la parametrització en termes d’error de salinitat. S’ha estudiat l’impacte de diverses dades auxiliars provinents de fonts diferents sobre l’error SSS final. Això permet tenir una primera impressió de l’error quantitatiu que pot esperar-se en les mesures reals futures, mentre que, en un altre estudi, s’ha investigat la possibilitat d’utilitzar senyals derivats de la reflectometria per tal de corregir les incerteses de l’estat del mar en el context SMOS. El nucli d’aquest treball el constitueix el Balanç d’Error SSS total. S’han identificat de forma consistent les fonts d’error i s’han analitzat els efectes corresponents en termes de l’error SSS mig en diferents configuracions d’algoritmes. Per una altra banda, es mostren els resultats d’un estudi de la variabilitat horitzontal de la salinitat, dut a terme utilitzant dades d’entrada amb una resolució espacial variable creixent. Això hauria de permetre confirmar la capacitat de la SSS recuperada per tal reproduir característiques oceanogràfiques mesoscàliques. Els principals resultats i consideracions derivats d’aquest estudi contribuiran a la definició de les bases de l’algoritme de recuperació de la salinitat.
Satellite oceanography has become a consolidated integration of conventional in situ monitoring of the oceans. Accurate knowledge of the oceanographic processes and their interaction is crucial for the understanding of the climate system. In this framework, routinely-measured salinity fields will directly aid in characterizing the variations of the global ocean circulation. Salinity is used in predictive oceanographic models, but no capability exists to date to measure it directly and globally. The European Space Agency’s Soil Moisture and Ocean Salinity (SMOS) mission aims at filling this gap through the implementation of a satellite that has the potential to provide synoptically and routinely this information. A novel instrument, the Microwave Imaging Radiometer by Aperture Synthesis, has been developed to observe the sea surface salinity (SSS) over the oceans by capturing images of the emitted microwave radiation around the frequency of 1.4 GHz (L-band). SMOS will carry the first-ever, polar-orbiting, space-borne, 2-D interferometric radiometer and will be launched in early 2009. Like whatsoever remotely-sensed geophysical parameter estimation, the retrieval of salinity is an inverse problem that involves the minimization of a cost function. In order to ensure a reliable estimation of this variable, all the other parameters affecting the measured brightness temperature will have to be taken into account, filtered or quantified. The overall retrieved product will thus be salinity maps in a single satellite overpass over the Earth. The proposed accuracy requirement for the mission is specified as 0.1 ‰ after averaging in a 10-day and 2ºx2º spatio-temporal boxes. In this Ph.D. Thesis several studies have been performed towards the determination of an ocean salinity error budget within the SMOS mission. The motivations of the mission, the rationale of the measurements and the basic concepts of microwave radiometry have been described along with the salinity retrieval main features. The salinity retrieval issues whose influence is critical in the inversion procedure are: • Scene-dependent bias in the simulated measurements, • Radiometric sensitivity (thermal noise) and radiometric accuracy, • L-band forward modeling definition, • Auxiliary data, sea surface temperature (SST) and wind speed, uncertainties, • Constraints in the cost function, especially on salinity term, and • Adequate spatio-temporal averaging. A straightforward concept stems from the statement of the salinity retrieval problem: different tuning and setting of the minimization algorithm lead to different results, and complete awareness of that should be assumed. Based on this consideration, the error budget determination has been progressively approached by evaluating the extent of the impact of different variables and parameterizations in terms of salinity error. The impact of several multi-sources auxiliary data on the final SSS error has been addressed. This gives a first feeling of the quantitative error that should be expected in real upcoming measurements, whilst, in another study, the potential use of reflectometry-derived signals to correct for sea state uncertainty in the SMOS context has been investigated. The core of the work concerned the overall SSS Error Budget. The error sources are consistently binned and the corresponding effects in terms of the averaged SSS error have been addressed in different algorithm configurations. Furthermore, the results of a salinity horizontal variability study, performed by using input data at increasingly variable spatial resolution, are shown. This should assess the capability of retrieved SSS to reproduce mesoscale oceanographic features. Main results and insights deriving from these studies will contribute to the definition of the salinity retrieval algorithm baseline.

This research evaluates and improves capabilities incorporated in the Water Rights Analysis Package (WRAP) modeling system for tracking salt loads, particularly for applications dealing with natural salt pollution problems that are prevalent in several major river basins in Texas and neighboring states. WRAP is the river/reservoir system simulation model incorporated in the Water Availability Modeling (WAM) System applied by agencies and consulting firms in Texas in planning and water right regulatory activities. A salinity simulation component of WRAP called WRAP-SALT was developed recently at Texas A&M University. WRAP-SALT was based on the premise of complete mixing within the monthly computational time step. However, salt concentrations actually have time variation throughout a reservoir. This thesis research investigates more realistic salinity routing methods. Historical gauged data provide a basis for calibration of routing parameters. The timing of the inflow load to determine outflow concentration is calculated by lag parameters with the monthly time steps. Complete mixing occurs during the lag months. Two options are incorporated into WRAP-SALT for setting the lag parameter. With the first option, the model-user sets a constant that is applied during every month of the simulation. This option requires calibration studies to determine the lag. With the alternative option, a variable lag is computed within the model in each month based on the concept of retention time, which is a representation of the time required for a monthly volume of water and its salt load to flow through a reservoir. When the lag is activated, the accuracy between observed and computed mean monthly salinity concentrations through the reservoir is generally improved. The basin-wide simulation was performed for the Brazos River Basin for conditions with and without salt control dams proposed by the Corps of Engineers. The proposed salt control impoundments improve water quality throughout the basin.

Morpho-physiological characterization and whole genome transcript profiling of rice genotypes that belongs to sub-species Indica, Japonica and wild relatives were carried out under salt stress. The existence of qualitatively different mechanisms of salt tolerance across the genotypes was identified. Multivariate analysis was applied to categorize the genotypes according to their level of tolerance. Modified SAM analysis elucidated the trait specific expression of genome wide transcripts. Gene ontology enrichment analysis identified the genes involved in different molecular functions such as signal transduction, transcription factor and ion homeostasis etc. Gene network analysis identified the regulatory network of genes that are active in different tissues. The differential expression of transcripts of four tolerant and two susceptible Indica genotypes under stress were further analysed. The candidate genes for different biological processes and molecular functions are identified and discussed. Highly induced stimulus responsive gene Os01g0159600 (OsLEA1a) and Os05g0382200 (Nhx) can be mentioned for instance. The differentially expressed genes that are located within the salt stress related QTLs were also identified. The transcriptomics data were also used to predict the salinity tolerance of genotypes using OSC-PLSDA model. The combined physiological and transcriptomic approach of this study gives a complementary whole organism assessment of plants responses to salt stress.

In the project "Mechanisms for Control of Leaf Growth during Salinity Stress" ionic and enzymatic changes in the cells and cell walls of the expanding region of salt-stressed maize leaves were evaluated. Conventional numerical techniques for REG estimation were reevaluated; 'Greens' method was recommended and applied throughout the project for growth intensity estimation. Salinity slowed leaf development and reduced leaf size, but increased cell development within the leaf-growing zone. Leaf elongation rate was most affected by salinity from the region of maximal growth to the distal end; the basal region was largely unaffected. Creep assays indicated that the physical properties of the cell wall were not altered. Furthermore, pH or protein concentrations in the apoplastic space were not altered. Salinity decreased in half the concentrations of putative oligosaccharides in both the apoplast and the Golgi vesicles, suggesting that salinity reduced oligosaccharide biosynthesis. Salinity significantly increased solute concentrations in the vacuoles, but the ion concentrations tested remain unchanged in the vacuole. Most importantly, salinity increased the ion concentrations in the apoplast, particularly Cl-concentrations. The evidence obtained clearly points to the biochemical and ionic components of the apoplast as otential factors controlling leaf elongation of salt-stressed plants.
