Geologist Jim Flocks presented recent research into the influence of the geologic framework on the evolution of nearshore shore-oblique sand ridges in the northern Gulf of Mexico at the NOAA Southeast Regional Office (SERO) speaker series. These ridges are fairly common in low-slope marine environments and provide important fisheries habitat. While progress has been made in understanding the growth of these ridges, few efforts have considered the influence of underlying geology on shoal formation and evolution. Flocks presented results from a case study of the Gulf Islands National Seashore demonstrating the importance of geology on nearshore shoal evolution. Results of the study were published in the Journal of Continental Shelf Research.

During HVO's early morning helicopter overflight along the coastline, orange streams of lava were entering the ocean in the vicinity of Ahalanui. Strong trade winds were pushing the white laze plumes inland.

Oceanographic and Water Quality Measurements in Chincoteague Bay, Maryland/Virginia, 2014 - 2015

The primary objective was to measure the physical response of the system to storm events, and identify processes that may affect estuarine resilience. Bottom landing platforms with instrumentation to measure currents, waves, water level, optical turbidity, water temperature, conductivity and water quality parameters were deployed at most sites.
