Impact of multiple stressors

The oceans are changing in multiple ways: Earth is warming, the oceans are acidifying, and certain oceanic regions are becoming stagnant. We are studying the impact of these stressors, singly and in concert, on an important group of marine meiofauna, benthic foraminifera.

The Harshest Habitats on Earth

  • We are studying the microbial eukaryote communities of haloclines in Deep Hypersaline Anoxic Basins that lie in > 3km of water in the Mediterranean Sea. My lab is dedicated to studies of the benthic protists; Virginia Edgcomb’s lab is studying the plantkic microbial communities and certain aspects of the benthos.  Read more about our collection expedition.
  • Additionally, we are investigating metazoan occurrences in the deep halocline / brines of these DHABs. Do animals truly inhabit hypersaline anoxic environments?
