Diverse studies predict global expansion of Oxygen Minimum Zones (OMZs) as a consequence anthropogenic warming. While the observed dissolved oxygen concentrations in many coastal regions are slowly decreasing, sediment core paleorecords often show contradictory trends. This is case for numerous high-resolution reconstructions oxygenation Eastern Tropical North Pacific (ETNP). major shifts redox conditions ETNP dominated by glacial-interglacial cycling, important fluctuations also occur...
Abstract The Chicxulub impact caused a crash in productivity the world's oceans which contributed to extinction of ∼75% marine species. In immediate aftermath extinction, export was locally highly variable, with some sites, including crater, recording elevated production. long‐term transition back more stable regimes has been poorly documented. Here, we present elemental abundances, foraminifer and calcareous nannoplankton assemblage counts, total organic carbon, bulk carbonate carbon...
To identify the main sources of terrigenous sediments La Paz Lagoon, a description hydrology drainage basins and mineralogy heavy fraction lagoon is needed.In this work, 14 sediment samples from arroyos (dry streams) 55 superficial marine were collected study area.The principal discharging into defined using geomorphologic analyses on Geographic Information Systems (GIS).The samples' grain size 3.25 -3.00 phi was obtained by sieving.The minerals separated bromoform mineralogical composition...
The Chicxulub impact caused a crash in export productivity much of the world’s oceans which contributed to extinction 75% marine species. In immediate aftermath extinction, local was highly variable, with some sites, including crater, recording elevated production. long-term transition back more stable regimes has been poorly documented. Here, we present elemental abundances, foraminifer and calcareous nannoplankton assemblage counts, total organic carbon, carbon isotopes from crater...
