Mid‐Miocene paleoproductivity in the Atlantic Ocean and implications for the global carbon cycle [PDF]

Paleoceanography, 2009
A prominent, middle Miocene (17.5–13.5 Ma) carbon isotope excursion ubiquitously recorded in carbonate sediments has been attributed to enhanced marine productivity and sequestration of 13 C depleted organic carbon in marine sediments or enhanced carbon burial in peat/lignite deposits on land.

Continental influence on the fertilization of marine waters during the late quaternary in the south of the Brazilian continental margin

Ocean and Coastal Research, 2022
This study sought to understand the role of continental influence on ocean productivity along the late Quaternary based on the comparison between continental palynomorphs and paleoproductivity proxies from the marine sediment core SIS188. Retrieved from

The use of fish remains in sediments for the reconstruction of paleoproductivity

IOP Conference Series: Earth and Environmental Science, 2009
The majority of the works concerning fish productivity are based in fish landing records. However, in order to understand the causes of variability in fish productivity (natural and/or anthropogenic) it is essential to have information from periods when human impacts (e.g., fisheries) are considered unimportant.

Eocene to Miocene U‐Pb Geochronology Evolution of the Rio Grande Rise, Southwestern Atlantic: A Paleoceanographic Approach

Paleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract The Rio Grande Rise (RGR) is a major submarine feature in the South Atlantic that plays an important role in regional oceanographic dynamics. This study presents new U‐Pb geochronology of sedimentary rocks from the RGR, offering direct age constraints on carbonate and apatite embedded within Fe‐Mn crusts and associated foraminifera fossils ...
