Combining altimetry and hydrography with inverse methods
We describe a generalization of the Bernoulli inverse method, which produces an estimate of Sea Surface Height (SSH) across the region of interest rather than simply at station positions. Real-time ‘float’ observations and satellite altimetry measurements are used to map a ‘sea surface elevation’ …

The general hydrography of the Mozambique Channel
The greater Agulhas Current system is believed to form a key link in the global ocean circulation since it is the inter-ocean conduit for warm Indian Ocean water to the Atlantic Ocean. This system has been thought to derive its water from the South Equatorial Current via two sources: the Mozambique …

The hydrography and heat fluxes between South Africa and Antarctica
Hydrographic sections between Africa and Antarctica; the A12, SR02 and SR02 sections conducted in 1990, 1990 and 1993 are presented here in comparison with the AJAX section of 1984. The numbered sections were undertaken as part of WOCE to better understand the ocean and the role it plays in the …

Hydrography and flow in the rift valley of the Mid-Atlantic Ridge
… have a significant impact on the rift-valley hydrography and dynamics but little is known about the details. Known processes of global importance acting near the axes of midocean ridges include high rates of diapycnal mixing associated with the rough topography and high-temperature …

The hydrography and dynamics of the general oceanic environment of the Prince Edward Islands
The Southern Ocean is the name given to the oceanic region that surrounds the entire Antarctic continent. It comprises the southern extents of the Atlantic, Indian and Pacific Oceans. The Antarctic continent forms the southern boundary of the Southern Ocean, while the northern border is not …

The hydrography and dynamics of rings and eddies of the Agulhas retroflection February-March 1987
The Agulhas Retroflection south of Africa is a dynamic region from which mesoscale rings and eddies are shed. Hydrographic data collected simultaneously during two dedicated research cruises in the Agulhas Retroflection region in February - March 1987 are analyzed in conjunction with satellite data …

Interannual variability and long-term trends of surface hydrography around the Prince Edward Island Archipelago, Southern Ocean
The Prince Edward Islands (PEIs) Archipelago are situated in a prime location for the study of ecosystem response to intrinsic climate variability in the Southern Ocean and the impact of climate change. They are positioned in the Polar Frontal Zone, which is constrained by the subAntarctic Front …

A description of the hydrography between Cape Town and Antarctica along the GoodHope Transect between 2004-2012
The Antarctic Circumpolar Current (ACC) within the Southern Ocean (SO) is the primary driver for global interoceanic exchanges. These exchanges form the foundation for the Meridional Overturning Circulation (MOC), a deep density driven circulation, which extends throughout the global oceans. The …

Relationship of plankton and marine snow to hydrography and currents on the southwest portion of Georges Bank during June 1997
… to quantify the relationships between plankton, hydrography, and currents and the fluxes through the RLR. Temperature-salinity-plankton diagrams and factor analysis revealed that most plankton taxa had characteristic relationships to the hydrography, with the exception of copepods which were …

Annual and Interannual Variability in the Wind Field and the Hydrography Along the Seward Line in the Northern Gulf of Alaska
<p>The Northeast Pacific GLOBEC (GLOBal ocean Ecosystems dynamics) program (October 1997 to December 2004) collected hydrographic data along the Seward Line that stretches from the inner shelf (GAM 59.8°N, 149.5°W) and extends over 200 km beyond the continental slope (GAK13 58.1°N, 147.8°W). The …

A geospatial deep learning framework for scalable hydrographic mapping
… In the United States, the National Hydrography Dataset (NHD) provides the authoritative spatial framework for surface water representation, yet its reliance on manual interpretation and rule-based workflows limits the timeliness and consistency of updates across diverse landscapes. …
