Understanding the nature of organic matter flux in the ocean remains a major goal of
oceanography because it impacts some of the most important processes in the ocean …

The ocean plays a central role in modulating the Earth's carbon cycle. Monitoring how the
ocean carbon cycle is changing is fundamental to managing climate change. Satellite …

Freshwater discharge from glaciers is increasing across the Arctic in response to
anthropogenic climate change, which raises questions about the potential downstream …

Diazotrophs are widespread microorganisms that alleviate nitrogen limitation in 60% of our
oceans, thereby regulating marine productivity. Yet, the group-specific contribution of …

The photosynthetic cyanobacterium Trichodesmium is widely distributed in the surface low
latitude ocean where it contributes significantly to N2 fixation and primary productivity …

Climate change manifestation in the ocean, through warming, oxygen loss, increasing
acidification, and changing particulate organic carbon flux (one metric of altered food …

Nitrogen fixation has a critical role in marine primary production, yet our understanding of
marine nitrogen-fixers (diazotrophs) is hindered by limited observations. Here, we report a …

Previous studies have shown that Saharan dust can be transported thousands of miles,
affecting regional climates, environments, and ecosystems. However, research on the long …

The oceanic biological carbon pump (BCP) regulates the Earth carbon cycle by transporting
part of the photosynthetically fixed CO2 into the deep ocean. Suppressing this mechanism …

The N 2-fixing cyanobacterium Trichodesmium is an important player in the oceanic nitrogen
and carbon cycles. Trichodesmium occurs both as single trichomes and as colonies …
