Flowing into the unknown: inferred paleodrainages for studying the ichthyofauna of Brazilian coastal rivers - paleodrainages shapefiles

Creator:

Thomaz, Andréa T. (UMICH) and Knowles, L. Lacey (UMICH)

Description:

The eastern coastal basins of Brazil are a series of small and isolated rivers that drain directly into the Atlantic Ocean. During the Pleistocene, sea-level retreat caused by glaciations exposed the continental shelf, resulting in enlarged paleodrainages that connected rivers that are isolated today. Using Geographic Information System (GIS), we infer the distribution of these paleodrainages, and their properties for the east Brazilian coast. Here, we publicly make available the shapefiles that demonstrate the paleodrainage structure along the Brazilian coast during the largest sea-level retreats in the Pleistocene, the riverine vectors during the same period and the coastal line for a drop of -125m in the sea.
