Have any sharks? Play GoFish and find out!

Scientists increasingly monitor what species are present in marine ecosystems as a way to figure out the health of that system and to detect if some species are threatened.

We Don’t Know the Half of It: Hundreds of Contaminants in Dolphin Blubber from Southern California

Dolphins and humans are continuously exposed to low levels of various halogenated, persistent manmade pollutants through their diets. In this study, blubber samples from 8 dolphins were analyzed by cutting-edge techniques to find out what’s accumulating in these marine predators. Findings suggest many routine monitoring programs underestimate the exposure of marine mammals to toxins. Carrie […]

Sea sponges soak up pollutants

Biomonitoring can be a great tool for measuring pollutants in marine ecosystems, but not all organisms accumulate chemicals equally. The sun sponge is being tested as a new and improved bioindicator for polycyclic aromatic hydrocarbons (PAHs). Zoe RugeI have a M.S. from the University of Rhode Island Graduate School of Oceanography, previously working with Dr. […]
