Whats Happening in the Neuse River 2019Apr04?

Hi all,

For the first time since Hurricane Florence, the estuary has some salt upstream of the bend at Cherry Point (station 120). The lower estuary is moderately stratified but the water is still cool and dissolved oxygen is > 8 mg/L throughout the estuary. There was a front between stations 60 and 70 with strong downstream gradients of temperature, pH, Chlorophyll fluorescence, and a spike in turbidity at station 70.

Best,

Nathan

What’s Happening in the Neuse 2019Mar18?

Hi all,

With flows just above average, the Neuse is starting to look more like an estuary, a really fresh estuary but at least with some salt at all the lower stations. Moderate chlorophyll values of ~20 were patchily distributed throughout the mid/lower estuary.

Best regards,         Nathan

What’s Happening in the Neuse River 2019Mar07?

Hi all,

Unbelievably, the estuary is fresher now than what we measured ten days after Hurricane Florence. Temperatures are cool and DO is high throughout the estuary. chl-a was generally less than 20 throughout the estuary except for a thin aggregation along the pycnocline at the lower stations. The dinoflagellate, Prorocentrum minimum, is famous for this and has been abundant for the last few trips.

Best,

Nathan

Hi all,

It’s still really fresh and the bloom downstream has gotten more dense. I looked at a sample from station 180S and the bloom is mostly Heterocapsa triquetra with lesser abundances of Prorocentrum minimum and Heterocapsa rotundata.  Again, these dinoflagellates don’t typically cause problems.

Best,

Nathan

 

 

Welcome to the Coastal and Environmental and Microbiological Processes Lab

The University of North Carolina – Chapel Hill’s Institute of Marine Sciences Coastal Environmental and Microbiological Processes Lab consists of graduate students, post-doctoral researchers, and technicians working on a variety of research projects addressing nutrient production dynamics of aquatic microbes at the base of the estuarine and coastal food webs. The Paerl Lab research focuses on environmental controls of algal (planktonic and benthic) production and community structure, as well as, the assessment of causes and consequences of human-induced eutrophication of rivers, lakes, estuaries and coastal oceans.
