Nitrogen is an essential nutrient for all life on Earth. It is, and likely has been, a critical
limiting nutrient controlling primary production rates in the oceans. The marine N budget is …

Decreasing concentrations of dissolved oxygen in the ocean are considered one of the main
threats to marine ecosystems as they jeopardize the growth of higher organisms. They also …

Decreasing concentrations of dissolved oxygen and the resulting expansion of anaerobic
ecosystems is a major threat to marine ecosystem services because it favors the formation of …

Abstract The Arabian Sea hosts a perennial and intense oxygen minimum zone (OMZ) at
150–1200 m depths with O 2 concentrations< 0.5 ml/l. It is generally believed that the …

Abstract The Indian Monsoon and the westerlies strongly influence the sedimentation in the
northeastern Arabian Sea by impacting rainfall and erosion on land and on biogeochemical …

Using high-precision and centennial-resolution ice core information on atmospheric nitrous
oxide concentrations and its stable nitrogen and oxygen isotopic composition, we …

Major and trace elemental geochemistry of a sediment core (SSK40/GC10; water depth∼ 50
m) from the eastern Arabian Sea (17° 59.89123 N, 72° 22.45161 E) have been investigated …

Abstract The Arabian Sea encompasses oxygen minimum zone with denitrifying conditions.
For the present study, sediments were collected across three transects off Goa transect (GT) …

Abstract The sediment core (MGS11/02), collected from the lower boundary of the Bay of
Bengal (BoB) oxygen minimum zone (890 m) is studied to understand the influences of …

The causes of organic-rich sediments in contact with the perennial oxygen minimum zone
(OMZ) on the continental slope off western India have been debated extensively, largely in …
