Measuring and monitoring eutrophication and hypoxia
(Global Environment Facility, Washington, 2011)
Coastal hypoxia is a complex problem and, although research has made great strides in understanding its causes and remedies, more knowledge is needed to fill critical gaps that impede action. To establish long-term trends ...
Historical records of coastal eutrophication-induced hypoxia
(European Geosciences Union, 2009)
Under certain conditions, sediment cores from coastal settings subject to hypoxia can yield records of environmental changes over time scales ranging from decades to millennia, sometimes with a resolution of as little as ...
Recent advances in the biogeochemistry of nitrogen in the ocean
(The European Geosciences Union, 2008)
Recent research has shown that marine nitrogen cycle is more dynamic, less well understood, and much more exciting than previously thought. However, despite impressive and rapid advances in our understanding of many important ...
Possible solar control on primary production along the Indian west coast on decadal to centennial timescale
(John Wiley, 2009)
Using multiple geochemical proxies including specific biomarkers (dinosterol, phytol, stigmasterol and beta-sitosterol) measured in a high-sedimentation rate core collected from the inner shelf (depth approx. 45 m) off Goa ...
Ocean biogeochemistry and atmospheric composition: Significance of the Arabian Sea
(Indian Academy of Sciences, 2000)
The Arabian Sea is an important site of biogeochemical ocean-atmosphere transfers, which play a crucial role in regulating the atmospheric chemical composition and the earth's climate. Widespread denitrification resulting ...
Multidisciplinary Observing in the World Ocean�s Oxygen Minimum Zone Regions: From Climate to Fish - The VOICE Initiative
(2019)
Multidisciplinary ocean observing activities provide critical ocean information to satisfy ever-changing socioeconomic needs and require coordinated implementation. The upper oxycline (transition between high and low oxygen ...
A non-diatom plankton bloom controlled by copepod grazing and amphipod predation: Preliminary results from the LOHAFEX iron-fertilisation experiment
(GLOBEC, 2009)
The most memorable LOHAFEX cruise came to an end on 17 March 2009 when RV Polarstern docked in the harbour of Punta Arenas (southern Chile) after successfully carrying out the longest iron fertilisation experiment so far ...
Benthic fluxes of methane along the salinity gradient of a tropical monsoonal estuary: Implications for CH4 supersaturation and emission
(Elsevier, 2018)
Observations in the Mandovi estuary, a typical tropical monsoonal estuary located on the west coast of India, revealed that waters were perennially supersaturated with CH4, indicating that the estuary could be a significant ...
AoA Region: The regional organization for the protection of the marine environment/regional commission for fisheries (ROPME/RECOFI) area
(UNESCO/IOC, 2009)
The ROPME/RECOFI or ROPME Sea Area includes eight countries, Bahrain, Iran, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates and contains part of the Arabian Sea LME.
Coastal biogeochemical processes in the north Indian Ocean (14, S-W)
