This study focuses on analysing the potential impact of the Amazon and Pará Rivers on the
salinity, temperature and hydrodynamics of the Western Tropical North Atlantic (WTNA) …

Abstract The Amazon Continental Shelf (ACS) has a coastline of∼ 1000 km and is situated
in a humid equatorial region with two distinct seasons, wet and dry, and two transitional …

At the mouth of the Amazon River, a widespread carbonate ecosystem exists below the river
plume, generating a hard-bottom reef (∼ 9500 km2) that includes mainly large sponges but …

Resumo SOURCE OR SINK? A REVIEW OF THE CO 2 FLUXES AT THE BRAZILIAN
CONTINENTAL SHELF. Studies of global carbon balance estimates are still incipient in the …

Abstract The Amazon River plume (ARP) has been shown to support high rates of nitrogen
fixation and primary production. However, nitrogen fixation alone cannot account for total …

We evaluated changes in the distributions of long-chain alkenones, long-chain diols and
GDGTs, lipids commonly used for paleothermometry, over the last 90 Myrs for sediments …

The delta-front estuaries of large rivers are crucial interfaces between lands and oceans,
being considered hotspots of vulnerability to the impact of climate changes due to several …

The high rates of N2 fixation observed in the Western Tropical Atlantic Ocean are powered,
at least in parts, by large influx of nutrients from the Amazon River. To disentangle the impact …

Biodiversity maintenance is a main goal in ecology. Hence, phytoplankton diversity and
biomass were analyzed in a coastal bay (Cumã Bay) of the Amazon Macrotidal Mangrove …

The western tropical Atlantic is strongly influenced by the Amazon, receiving the full
discharge from the largest river basin of the world. In order to ascertain the coastal-oceanic …
