Tropical Storm Arthur passed through ENC early Monday morning and dropped 3.36 in of rain in 0.5 hours (1:20am – 1:50am) recorded by Dr. Hans Paerl’s personal rain gauge. The photo above shows data output from the rain gauge showing the relative wind speed, wind direction, and rainfall. You can see more local weather reports of TS Arthur on the Community Collaborative Rain, Hail and Snow Network (CoCoRaHS). Hans’s report is also recorded on the CoCoRaHS site under the station name Beaufort 1.6 ENE and number NC-CR-151.
Since I’ve last reported on conditions in the Neuse River Estuary our world has changed a lot more than it has. Nothing exceptional to report water quality-wise. The high chl-a at stations 120 and 140 during March were likely remnants of the dinoflagellate bloom noticed in February. I’ll find out once I’m able to get back to the lab. Y’all stay safe and well.
The entire Paerl Lab would like to congratulate both students, Haley Plaas and Malcolm Barnard for their recent accomplishments. Haley was awarded a National Science Foundation Graduate Fellowship, which you can read more about here and Malcolm received an Honorable Mention for his application. Way to go!

Dr. Hans Paerl and Dr. Nathan Hall discussed the Status of NC’s estuarine water quality yesterday at the Clean Waters and SAV (submerged aquatic vegetation) workshop. Their presentations focused on existing and developing water quality management strategies, past and present estuarine water quality challenges, and water quality monitoring and assessment. Their participation in this workshop helped provide input for the NC Coastal Habitat Protection Plan revision to develop collaborative management strategies to preserve and improve water quality suitable for SAV growth in NC coastal waters.

That line of strong storms with torrential rains on Feb 6 and 7th has increased Neuse River flows to about five times their average for this time of year. The turbid (>20 NTU) flood waters are clearly evident upstream of New Bern (stations 0-30). Downstream of New Bern, the estuary was highly stratified. Waters are quite warm for this time of year and bottom water DO was well below saturation from station 50 to 100. A near surface zone of elevated chl-a (~30 ug/L) occurred at station 160.

PhD students Haley Plaas and Malcolm Barnard are assisting with SciREN-Coast this year. SciREN-Coast is a community of educators and researchers based in eastern North Carolina who share resources to promote science literacy in today’s youth. Haley is a member of the logistics team and Malcolm is a member of the education team. To learn more about SciREN-Coast and their upcoming events click here.
PhD student Haley Plaas recently gave a talk at the NC Museum of Natural Sciences about how air quality might be impacted by cyanobacteria toxin production. You can watch her presentation here.
