  • The Mean Flow Field of the Tropical Atlantic Ocean
    Deep-Sea Research II 46 (1999) 279—303 The mean flow field of the tropical Atlantic Ocean Lothar Stramma*, Friedrich Schott Institut fu( r Meereskunde, an der Universita( t Kiel, Du( sternbrooker Weg 20, 24105 Kiel, Germany Received 26 August 1997; received in revised form 31 July 1998 Abstract The mean horizontal flow field of the tropical Atlantic Ocean is described between 20°N and 20°S from observations and literature results for three layers of the upper ocean, Tropical Surface Water, Central Water, and Antarctic Intermediate Water. Compared to the subtropical gyres the tropical circulation shows several zonal current and countercurrent bands of smaller meridional and vertical extent. The wind-driven Ekman layer in the upper tens of meters of the ocean masks at some places the flow structure of the Tropical Surface Water layer as is the case for the Angola Gyre in the eastern tropical South Atlantic. Although there are regions with a strong seasonal cycle of the Tropical Surface Water circulation, such as the North Equatorial Countercurrent, large regions of the tropics do not show a significant seasonal cycle. In the Central Water layer below, the eastward North and South Equatorial undercurrents appear imbedded in the westward-flowing South Equatorial Current. The Antarcic Intermediate Water layer contains several zonal current bands south of 3°N, but only weak flow exists north of 3°N. The sparse available data suggest that the Equatorial Intermediate Current as well as the Southern and Northern Intermediate Countercurrents extend zonally across the entire equatorial basin. Due to the convergence of northern and southern water masses, the western tropical Atlantic north of the equator is an important site for the mixture of water masses, but more work is needed to better understand the role of the various zonal under- and countercur- rents in cross-equatorial water mass transfer.

  • Fronts in the World Ocean's Large Marine Ecosystems. ICES CM 2007
    - 1 - This paper can be freely cited without prior reference to the authors International Council ICES CM 2007/D:21 for the Exploration Theme Session D: Comparative Marine Ecosystem of the Sea (ICES) Structure and Function: Descriptors and Characteristics Fronts in the World Ocean’s Large Marine Ecosystems Igor M. Belkin and Peter C. Cornillon Abstract. Oceanic fronts shape marine ecosystems; therefore front mapping and characterization is one of the most important aspects of physical oceanography. Here we report on the first effort to map and describe all major fronts in the World Ocean’s Large Marine Ecosystems (LMEs). Apart from a geographical review, these fronts are classified according to their origin and physical mechanisms that maintain them. This first-ever zero-order pattern of the LME fronts is based on a unique global frontal data base assembled at the University of Rhode Island. Thermal fronts were automatically derived from 12 years (1985-1996) of twice-daily satellite 9-km resolution global AVHRR SST fields with the Cayula-Cornillon front detection algorithm. These frontal maps serve as guidance in using hydrographic data to explore subsurface thermohaline fronts, whose surface thermal signatures have been mapped from space. Our most recent study of chlorophyll fronts in the Northwest Atlantic from high-resolution 1-km data (Belkin and O’Reilly, 2007) revealed a close spatial association between chlorophyll fronts and SST fronts, suggesting causative links between these two types of fronts.

  • Northwest African Upwelling Scenario
    OCEANOLOGICA ACTA ⋅ VOL. 24 – Supplement Northwest African upwelling scenario Eberhard HAGEN* Baltic Sea Research Institute, Seestrasse 15, 18119 Warnemuende, Germany Received 24 December 1999; revised 15 May 2000; accepted 16 May 2000 Abstract − Observations, hypotheses and derived scenarios are discussed for the Northwest-African coastal upwelling area. The process of coastal upwelling is considered to be composed of a climatic steady-state part and fluctuations acting on different spatial and temporal scales. Attention is focused on disturbances acting globally on the inter-annual time-scale. El Niño-like changes occur in the system of trade winds and modify the equatorial regime of currents as well as the coastal upwelling regimes on both flanks of the Inter-tropical Convergence Zone. There is an opposite thermal response in near-surface layers along the zonal coast in the Gulf of Guinea and along the meridional coast off NW-Africa. Off the continental slope of Senegal and Mauritania, the poleward undercurrent is linked with the system of eastward flowing equatorial undercurrents via the transport of South Atlantic Central Water (SACW) around the eastern flank of the Guinea Dome. The upwelling undercurrent partly feeds its SACW properties into the belt of coastal upwelling and contributes significantly to the biological productivity during ‘normal’ and ‘abnormal’ upwelling years. Future investigations should focus on changes in the time-scale of decades. © 2001 Ifremer/CNRS/IRD/Éditions scientifiques et médicales Elsevier SAS Résumé − Upwelling au nord-ouest de l‘Afrique. La zone d’upwelling située au nord-ouest des côtes africaines est étudiée dans le cadre d‘une discussion portant sur les observations, les hypothèses et les scénarios qui en dérivent.

  • Mapping Climatological Seasonal Variations of Surface Currents in the Tropical Atlantic Using Ship Drifts
    JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 91, NO. C9, PAGES 10,537-10,550, SEPTEMBER 15, 1986 Mapping Climatological Seasonal Variations of Surface Currents in the Tropical Atlantic Using Ship Drifts PHILIP L. RICHARDSON AND DAVID WALSH Woods Hole Oceanographic Institution, Woods Hole, Massachusetts The seasonal variability of current velocities in the tropical Atlantic was studied by grouping ship drift velocity observations into 2ø x 5ø boxes and calculating monthly mean velocity values. These values were used to calculate and map the annual mean velocity, the seasonal variation about the mean, the annual and semiannual harmonics, and the first two empirical orthogonal functions (EOFs). The seasonal variation is primarily zonal in the equatorial band and in the North Equatorial Countercurrent (NECC) and primarily alongshore near the coast of South America. Maxima of seasonal variation of 23 cm/s are centered in the NECC near 6øN, 42.5øW and in the Gulf of Guinea near 2øN, 7.5øW. Most (-80%) of the variance in the NECC and along the western boundary of the area studied has an annual period; most of the variance along the equator in the mid-Atlantic has a semiannual period. Over the whole region, 49% of the seasonalvariance is explained by the annual harmonic, and 69% is explained by a combination of the annual and semiannual harmonics. The second EOF contains 29% of the variance of the data set and shows a simultaneousspeeding (slowing) of the major equatorial currents (the South Equatorial Current (SEC), the North Brazil Current, the NECC, and the Guinea Current) along their principal axes of variation with a concurrent slowing (speeding) of the Guyana Current and the Brazil Current.

  • Global Ocean Surface Velocities from Drifters: Mean, Variance, El Nino–Southern~ Oscillation Response, and Seasonal Cycle Rick Lumpkin1 and Gregory C
    JOURNAL OF GEOPHYSICAL RESEARCH: OCEANS, VOL. 118, 2992–3006, doi:10.1002/jgrc.20210, 2013 Global ocean surface velocities from drifters: Mean, variance, El Nino–Southern~ Oscillation response, and seasonal cycle Rick Lumpkin1 and Gregory C. Johnson2 Received 24 September 2012; revised 18 April 2013; accepted 19 April 2013; published 14 June 2013. [1] Global near-surface currents are calculated from satellite-tracked drogued drifter velocities on a 0.5 Â 0.5 latitude-longitude grid using a new methodology. Data used at each grid point lie within a centered bin of set area with a shape defined by the variance ellipse of current fluctuations within that bin. The time-mean current, its annual harmonic, semiannual harmonic, correlation with the Southern Oscillation Index (SOI), spatial gradients, and residuals are estimated along with formal error bars for each component. The time-mean field resolves the major surface current systems of the world. The magnitude of the variance reveals enhanced eddy kinetic energy in the western boundary current systems, in equatorial regions, and along the Antarctic Circumpolar Current, as well as three large ‘‘eddy deserts,’’ two in the Pacific and one in the Atlantic. The SOI component is largest in the western and central tropical Pacific, but can also be seen in the Indian Ocean. Seasonal variations reveal details such as the gyre-scale shifts in the convergence centers of the subtropical gyres, and the seasonal evolution of tropical currents and eddies in the western tropical Pacific Ocean. The results of this study are available as a monthly climatology. Citation: Lumpkin, R., and G.

Cruz, P-9901, Horta, Azores, Portugal Abstract. Many tropical reef ®shes are divided into Atlantic and East Paci®c taxa, placing similar species in two very different biogeographic regimes. The tropical Atlantic is a closed ocean basin with relatively stable currents, whereas the East Paci®c is an open basin with unstable oceanic circulation. To assess how evolutionary processes are in¯uenced by these differences in oceanography and geography, we analyze a 630-bp region of mitochondrial cyto- chrome b from 171 individuals in the blenniid genus Ophioblennius. Our results demonstrate deep genetic structuring in the Atlantic species, O. atlanticus, corresponding to recognized biogeographic provinces, with divergences of d 5 5.2±12.7% among the Caribbean, Brazilian, St. Helena/Ascension Island, Gulf of Guinea, and Azores/Cape Verde regions. The Atlantic phylogeny is consistent with Pliocene dispersal from the western to eastern Atlantic, and the depth of these separations (along with prior morphological comparisons) may indicate previously unrecognized species. The eastern Paci®c species, O. steindachneri, is characterized by markedly less structure than O. atlanticus, with shallow mitochondrial DNA lineages (dmax 5 2.7%) and haplotype frequency shifts between locations in the Sea of Cortez, Paci®c Panama, Clipperton Island, and the Galapagos Islands.

VEITCH South African Environmental Observation Network, Egagasini Node, Cape Town, South Africa (Manuscript received 26 May 2016, in final form 20 March 2017) ABSTRACT The northern Gulf of Guinea is a part of the eastern tropical Atlantic where oceanic conditions due to the presence of coastal upwelling may influence the regional climate and fisheries. The dynamics of this coastal upwelling is still poorly understood. A sensitivity experiment based on the Regional Oceanic Modeling System (ROMS) is carried out to assess the role of the detachment of the Guinea Current as a potential mechanism for coastal upwelling. This idealized experiment is performed by canceling the inertia terms re- sponsible for the advection of momentum in the equations and comparing with a realistic experiment. The results exhibit two major differences.

Strong coastal upwelling and the Congo River strongly influence primary production. Much of the present knowledge of the South East Atlantic has been derived from ship-borne measurements and in situ sensors, which cannot generally provide extensive spatial and tem- poral coverage. Similarly, previous satellite studies of the region have often focused on small spatial areas and limited time periods. This paper provides an improved understanding of seasonal and interannual variability in ocean dynamics along the South East Atlantic coast of Africa using time series of satellite and model derived data products. Eighteen years of satellite sea surface temperature data are complimented by 7 years of sea level data.

Aquarone and S. Adams The California Current LME is bordered by the USA and Mexico, between subtropical and subarctic LMEs. It has a surface area of around 2.2 million km², of which 1.31% is protected, and it contains 0.01% of the world’s coral reefs and 1.04% of the world’s sea mounts (Sea Around Us 2007). The LME shoreline is more than two thousand miles long. The LME features more than 400 estuaries and bays, including the Columbia River, San Francisco Bay and Puget Sound, which constitute 61% of the estuary and bay acreage. This LME is characterised by its temperate climate and strong coastal upwelling. Book chapters and articles pertaining to this LME include MacCall (1986), Mullin (1991), Bakun (1993), Bottom et al. (1993), McGowan et al. (1999), Brodeur et al. (1999) and Lluch- Belda et al. (2003). Additional information on this well-studied LME is available from the Pacific Marine Environmental Laboratory at< www.pmel.noaa.gov>. I. Productivity The effects of coastal upwelling, ENSO and the Pacific Decadal Oscillation (PDO) result in strong interannual variability in the productivity of the ecosystem and, consequently, of the catch levels of different species groups (Bakun 1993). ENSO events are characterised locally by an increase in temperature, a rise in coastal sea level, diminished upwelling and increased coastal rainfall (Bakun 1993).
