Our lab troops (Malcolm, Haley, Jeremy) are currently conducting nutrient bioassays, determining which nutrients are responsible for the current toxic cyanobacterial bloom spreading through Lake Erie (see URL below). This is part of the NSF-NIH supported Oceans and Human Health Lake Erie Center, that we are part of. Talk about good timing!!

For her honors thesis Felix prepares a bioassay where she hopes to determine a relationship between harmful algal bloom formation and changes to salinity in the Chowan River of coastal North Carolina, in light of climate change-driven changes to hydrologic event patterns.

I’m a little behind but here are the results from the last Neuse run on 9 July. It’s crazy how things have changed since spring when the estuary was basically a river. Salinities in the bottom waters of the lower estuary are as high as I remember seeing. The only other time that bottom waters at 180 have been this high was on 5 Oct 2002. Neuse river flows do not indicate that we are in as significant of a drought as in 2002. So, I think something on the ocean-side of the estuary might be playing a role in the high salinities and plan to see what our physical oceanographers think. The estuary was strongly stratified from New Bern to the mouth. Bottom waters were anoxic along much of the transect as evidenced by a strong sulfide smell. The crew will be out again next week.
