Summary

Geochemical and isotopic compositions were determined in stream sediment and parent rocks collected in April 2017 and June 2017 and in nearshore sediment collected bimonthly in sediment traps from May 2017 to June 2018 in the coastal zone and 12 drainages of southwest Puerto Rico: Rio Loco, Yauco, Guayanilla, Macana, Tallaboa, Matilde, Portugues, Bucana, Inabon, Jacaquas, Descalabrado, and Coamo. Geochemical compositional data include: a) total contents of major, minor, trace, and rare earth elements in the <0.063 mm-diameter fraction of terrestrial (n=53) and nearshore sediment (n=63) and powdered rocks (n=19) analyzed by inductively coupled plasma optical emission spectroscopy (ICP-OES) and inductively coupled plasma mass spectroscopy [...]

Purpose

Geochemical and isotopic compositions of terrestrial sediment and parent rocks show the source, fate, and timing of runoff from southwest Puerto Rico watersheds to nearshore coral reefs. Sample collection for the study spanned pre- and post-hurricane conditions in the coastal region associated with Hurricanes Irma and Maria in September 2017. Knowledge about terrestrial runoff sources can identify watershed where restoration and erosion control activities are most needed.
