Although over a dozen elements are needed to support phytoplankton growth, only a few are considered to be growth-limiting. As the central atom in vitamin B12, cobalt is crucial for metabolism, but its status as a limiting nutrient is uncertain. This thesis investigates the geochemical controls on oceanic cobalt scarcity and their biological consequences. Analysis of over 1000 samples collected in the Tropical Pacific Ocean reveals a dissolved cobalt distribution that is strongly coupled to dissolved oxygen, with peak concentrations where oxygen is lowest. Large cobalt plumes within anoxic waters are maintained by three processes: 1) a cobalt supply from organic matter remineralization, 2) an amplified sedimentary source from oxygen-depleted coastlines, and 3) low-oxygen inhibition of manganese oxidation, which scavenges cobalt from the water column. Rates of scavenging are calculated from a global synthesis of recent GEOTRACES data and agree with cobalt accumulation rates in pelagic sediments. Because both sources and sinks are tied to the extent of oxygen minimum zones, oceanic cobalt inventories are likely dynamic on the span of decades. Despite extremely low cobalt in the South Pacific gyre, the cyanobacterium Prochlorococcus thrives. Minimum cobalt and iron requirements of a Prochlorococcus strain isolated from the Equatorial Pacific are quantified. Cobalt quotas are related to demand for ribonucleotide reductase and methionine synthase enzymes, which catalyze critical steps in DNA and protein biosynthesis, respectively. Compared to other cyanobacteria, a streamlined metal physiology makes Prochlorococcus susceptible to competitive inhibition of cobalt uptake by low levels of zinc. Although phytoplankton in the Equatorial Pacific are subject to chronic iron-limitation, widespread cobalt scarcity and vulnerability to zinc inhibition observed in culture imply that wild Prochlorococcus are not far from a cobalt-limitation threshold.

Analysis of vertical profiles of absolute horizontal velocity collected in January 1981, February 1982 and April 1982 in the central equatorial Pacific as part of the Pacific Equatorial Ocean Dynamics (PEQUOD) program, revealed two significant narrow band spectral peaks in the zonal velocity records, centered at vertical wavelengths of 560 and 350 stretched meters (sm). Both signals were present in all three cruises, but the 350 sm peak showed a more steady character in amplitude and a higher signal-to-noise ratio. In addition, its vertical scales corresponded to the scales of the conspicuous alternating flows generically called the equatorial deep jets in the past (the same terminology will be used here). Meridional velocity and vertical displacement spectra did not show any such energetic features. Energy in the 560 sm band roughly doubled between January 1981 and April 1982. Time lagged coherence results suggested upward phase propagation at time scales of about 4 years. East-west phase lines computed from zonally lagged coherences, tilted downward towards the west, implying westward phase propagation. Estimates of zonal wavelength (on the order of 10000 km) and period based on these coherence calculations, and the observed energy meridional structure at this vertical wavenumber band, seem consistent, within experimental errors, with the presence of a first meridional mode long Rossby wave packet, weakly modulated in the zonal direction. The equatorial deep jets, identified with the peak centered at 350 sm, are best defined as a finite narrow band process in vertical wavenumber (311-400 sm), accounting for only 20% of the total variance present in the broad band energetic background. At the jets wavenumber band, latitudinal energy scaling compared well with Kelvin wave theoretical values and a general tilt of phase lines downward towards the east yielded estimates of 10000-16000 km for the zonal wavelengths.

Texto completoA radiometria da cor do oceano oferece informações essenciais para estudos de produtividade primária, fluxos de calor e ciclos biogeoquímicos na superfície dos oceanos. Modelos generalizados de cor do oceano que relacionam dados radiométricos de satélite com variáveis biogeoquímicos são desenvolvidos com bases de dados globais in situ. No entanto, quando aplicados a regiões específicas estes modelos apresentam desvios significativos que estão relacionados a incertezas nas medidas in situ e satelitais, e sub-representações da variabilidade da cor do oceano. Portanto, para a melhoria de produtos de cor do oceano é preciso conhecer melhor as fontes incertezas das medidas e a variabilidade bio-óptica em diferentes regiões oceânicas. O presente trabalho teve como foco os Oceanos Atlântico Sul Sub-tropical e Pacífico Sudeste abrangendo importantes províncias biogeográficas com águas opticamente distintas. Dados in situ foram coletados durante uma campanha de verão a bordo do navio de pesquisa R/V Melville (MV1102). A primeira parte do trabalho compreendeu análises de incertezas dos dados radiométricos e bio-ópticos com três objetivos principais: a) a comparação de diferentes técnicas de amostragem com instrumentos emersos e submersos; b) comparações com a reflectância de sensoriamento remoto (Rsr) modelada; e c) análises dos impactos das incertezas em modelos operacionais de cor do oceano. As análises de incertezas revelaram níveis de altos a moderados associados às diferentes técnicas, com diferenças relativas (DR) de 12 a 26\% para as bandas de cor do oceano (412-555 nm) e 3 a 12% para as razões de bandas (412-510/555). O uso de uma medida de Rsr integrada (Instrumentos, INS) reduziu as incertezas já que cada técnica individual estava sujeita a diferentes erros instrumentais e ambientais. O ajuste perfeito com a Rsr modelada não foi obtido, principalmente para as estações com condições ambientais mais adversidades (de vento, ondas e nuvens), com 18-34\% DR para as bandas espectrais. Ainda assim, o impacto das incertezas do INS foi de modo geral, menor que os erros intrínsecos aos modelos empíricos e semi-analíticos (SA) de cor do oceano. Dessa forma, os métodos empregados para obter medidas mais acuradas foram razoavelmente eficazes em reduzir as incertezas. Desvios significativos dos modelos de cor do oceano foram relacionados à variabilidade óptica da região de estudo e erros intrínsecos aos modelos. A segunda parte da investigação compreendeu análises das fontes de variabilidade bio-óptica e suas relações com as variáveis biogeoquímicas nas diferentes províncias. A distribuição dominante das propriedades ópticas inerentes (POIs) esteve associada ao gradiente de concentração de clorofila a (Cla). Variações de segunda ordem foram relacionadas a POIs específicas associadas à estrutura da comunidade fitoplanctônica, a composição e distribuição do tamanho das partículas e à variabilidade da matéria orgânica dissolvida e particulada (MODP). Para sintetizar as variações de primeira e segunda ordem na região de estudo, uma classificação Regional de Tipos Específicas de Águas Ópticas (R-TEAO) foi proposta para definir 5 classes, integrando as POIs específicas e índices bio-ópticos, i.e., o Índice de tamanho do fitoplâncton, índice de CDM, o coeficiente especifico de retroespalhamento das partículas (bbp/Cla) e o parâmetro de variação espectral ($\eta$). O R-TEAO melhorou significativamente o desempenho de modelos SA com parametrizações especificas para cada classe, reduzindo a DR do bbp do modelo GSM01 (Garver-Siegel-Maritorena) de 35 a 9\% e o coeficiente de absorção do MODP de 30 a 23\% para o modelo QAAv5 (Quase Analytical Algorithm). Para águas mais opticamente complexas a melhoria dos modelos foi ainda mais significativa. Análises das variações espaço-temporais das relações ópticas e a aplicabilidade do R-TEAO para estações sazonais diferentes e outras regiões oceânicas, são recomendadas para pesquisas futuras. O método tem potencial de ser aplicado para a melhoria de produtos de cor do oceano por satélite e ser usado como um novo produto integrando informações importantes para estudos biogeoquímica.

Texto completoInteractions between a tropical cyclone (TC) and the underlying ocean environment can have significant impacts on physical mechanisms during the formation and intensification of the storm. During the summer of 2010, the Impact of Typhoons on the Ocean in the Pacific (ITOP) program was conducted to examine interactions between the ocean and TCs using a variety of experimental approaches. Specific observational assets included an array of moored buoys, two WC-130J aircraft, and a U.S. research vessel (RV Revelle). Airborne-deployed sensors included dropwindsondes, airborne expendable bathythermographs (AXBTs), Lagrangian floats, and drifters. In this thesis, AXBT observations were used to examine basic characteristics of the ocean environment during TCs that occurred during ITOP. Observations were compared to the Naval Research Laboratory East Asian Seas Nowcast Forecast System (NRL EASNS). For high ocean heat content (OHC), the model analyzed OHC was too low and for low OHC, the model analyses were too high. The largest analyzed and observed differences were found to occur in regions of TC-induced ocean changes. The significance of this comparison is the contribution to understanding the relationship between OHC and TC structure, with specific focus on the representation in the operational NRL EASNFS.

In the subpolar region in the southern hemisphere, the Antarctic Circumpolar Current (ACC) is one of the main sources of the Peru Current. The ACC plays an important role in the climate change of the world. The fluctuations in the ACC intensity of the western South Atlantic Ocean consequentially influence the SST (Sea Surface Temperature) and marine ecosystems. However, the variations in the SST in the Southern Ocean have rarely been addressed. It is because the South Atlantic Ocean is rarely sampled and studied tied to its inclement weather and rigorous environment in the area. FFT, Wavelet, Empirical Orthogonal Function (EOF), Ensemble Empirical Mode Decomposition (EEMD), Harmonic analysis, Cross-Correlation Analysis (Xcorr) and low pass filter methods are applied to a 147-year (1870-2016) time series dataset of SST distributed by the Met Office Hadley Centre. We find that there are the obvious inter-annual and inter-decadal variations existing in our study area. The results show that SSTAs in the oceans west and east of the South America and Antarctic Peninsula have respectively strong positive (R = 0.56) and negative (R = −0.67) correlations with the Niño 3.4 SSTA. We further show that, statistically, the temporal variations in the SSTAs of the ACC lead the Niño 3.4 SSTA by four to six months. Such findings imply that change in the strength of El Niño-Southern Oscillation (ENSO) or circulation under the changing climate could change the climate in regions at higher latitudes as well. EOF analyses show the particularly negative correlations (R=-0.56) with Pacific Decadal Oscillation (PDO) periods. This study further showed that changes in SSTAs in the regions mentioned above were enlarged when the PDO and the ENSO were in the same warm or cold phase, implying that changes in the SST of higher latitude oceans could be enhanced when the influence of the ENSO is considered along with the PDO. Furthermore, we analyzed the cross-correlation between the Brazil-Malvinas Confluence Zone (BMC) and PDO indexes. The result showed that the BMC index had a strong positive correlation (R=0.75) with the PDO index, when the PDO index time series led by 3 to 4 years of the BMC index time series. Such a duration was similar to the periodicity of a typical ENSO event, implying that variations in BMC index might reflect both the ENSO and PDO events.

The result for global greenhouse gas is from industrialization in IPCC AR4, CO2 is the most greenhouse gas (GHG) radiative forcing of climate between 1750 and 2005. Wanninkhof [1992] analysis global sea uptake CO2 is 2.2(+22% between -19%)Pg C per year. Ocean occupied the earth surface 70%, but the ocean surface air CO2 is too sparse, so we have use island CO2 observation data or program project vessel observation. Global CO2 observations have four type: 1. Ground observation: The ground base stations in the WDCCG (World Data Centre for Greenhouse Gases) have to map out; it includes ship observation, aircraft observation, and ground based observation; 2. Aircraft observation : MOZAIC has been from 1993A.D. based on EU and Boeing Company suggestion, it is major in observation O3, H2O, CO, and NOx, CARIBIC is suggest in germen airline from 1997 A.D., it major in greenhouse gas and aerosols. IAGOS had been 2006 A.D. combine MOZAIC and CARIBIC; CONTRAIL had been star from 1993 A.D, major in CO2 and CH4; 3. Satellite observation: Envisat, Europe satellite takes with CIAMACHY, MIPAS, and GOMOS. AQUA, US takes with AIRS to observation CO2, GOSAT, Japan, major observation CO2;4.

Texto completoDrivers that influence oceanic productivity are not clearly constrained. However, sea level changes during glacial cycles have been proposed as a potential driver for productivity variations observed over warm and cold climate periods. In order to determine this, additional oceanic paleoproductivity data collection is necessary to estimate the ocean’s feedback in response to a dynamic climate. The eastern equatorial Pacific (EEP) is an ideal site for productivity studies due to its high levels of nutrients and deep upwelling. This research examines the phosphorous and barite geochemisty of four EEP sites while also comparing the sites’ glacial and interglacial productivity variations to the geochemistry and productivity results of an independent central equatorial pacific site. Phosphorus and other elemental data were collected from sites 845, 848, 849, and 853 (ODP Leg 138). Using a Ba/Ti and P/Ti proxy (“excess” proxies), distinct productivity variations during glacial and interglacial periods were observed. While the age model for these sites has been estimated, the observed variations more than likely agree with high productivity during glacial periods and lower productivity during interglacial periods. Central equatorial Pacific cores RR0603-03TC and RR0603-03JC (IODP site survey cruise for Proposal 626) have been used as a reference for geochemical concentration parameters, as well as a comparison tool for productivity variations among the central and eastern sites. The central equatorial geochemistry results provided support for sea level changes driving paleoproductivity variations. The similar variation patterns displayed by the EEP’s geochemical data in this research could provide additional support for this hypothesis.
