Metal concentrations below or at the typical lower limit for marine slope sediments. Metals originate from continental inputs to the continental shelf and eroded and transported from there to the slope region. No anthropic influence was detected on metal concentrations.

Studies published between 2000 and early 2022 about the CO2 fluxes show that, in general, the Brazilian continental shelf behaves as a sink of atmospheric CO2 at its north and south areas, and as a source of CO2 at the northeast and southeast regions. However, the presence of different coastal ecosystems and the seasonal variability can change those behaviors.

The variation of pH in the estuarine systems follows the biogeochemical properties and the salinity contributes to the buffering capacity that maintain the seawater pH (~ 8) stable (1). The pH decreasing (acidification) affects the water properties influencing the nutrients balance. PID flux shows a behavior that is related to the sediment texture, biota presence, pH and salinity variation (2).
