NOAA is soliciting proposals to increase our understanding of the combined impacts of multiple stressors, including harmful algal blooms, deoxygenation, ocean acidification, and increasing temperatures, on the function and health of marine ecosystems within the context of climate change. NOAA expects to fund 1–2 projects for up to four years in duration, with an approximate annual budget of $1 million, not to exceed $4 million in total.
