About

Harvey Seim is a professor in the Department of Earth, Marine and Environmental Sciences at the University of North Carolina at Chapel Hill. His research focuses on observational physical oceanography, operating observing platforms to measure physical properties in the ocean, atmosphere, or lakes. He pursues analyses to improve understanding of the fluid dynamics of the sampled environment, employing a variety of autonomous observing technologies such as bottom moorings, meteorological buoys, underwater gliders, and high-frequency radar. He also participates in shipboard sampling efforts. On campus, his activities are largely devoted to analyses, which can be descriptive, empirical, or testing simplified models against observations.

• Declines and recovery in endangered Galapagos pinnipeds during the El Niño event

  Scientific Reports · 2021 · 47 citations

  Currently, the Galapagos sea lion (GSL, Zalophus wollebaeki) and Galapagos fur seal (GFS, Arctocephalus galapagoensis) are among the most important endemic species for conservation in the Galapagos Archipelago. Both are classified as "Endangered" since their populations have undergone drastic declines over the last several decades. In this study we estimated the abundance of both otariids, and their population trends based using counts conducted between 2014 and 2018 in all their rookeries, and…

• Annual and Seasonal Surface Circulation Over the Mid‐Atlantic Bight Continental Shelf Derived From a Decade of High Frequency Radar Observations

  Journal of Geophysical Research Oceans · 2020-10-12 · 29 citations

  articleOpen access

  Abstract A decade (2007–2016) of hourly 6‐km‐resolution maps of the surface currents across the Mid‐Atlantic Bight (MAB) generated by a regional‐scale High Frequency Radar network are used to reveal new insights into the spatial patterns of the annual and seasonal mean surface flows. Across the 10‐year time series, temporal means and interannual and intra‐annual variability are used to quantify the variability of spatial surface current patterns. The 10‐year annual mean surface flows are weaker…

• Overview of the Processes Driving Exchange at Cape Hatteras Program

  Oceanography · 2022-01-01 · 21 citations

  articleOpen access1st authorCorresponding

  The Processes driving Exchange At Cape Hatteras (PEACH) program seeks to better understand seawater exchanges between the continental shelf and the open ocean near Cape Hatteras, North Carolina. This location is where the Gulf Stream transitions from a boundary-trapped current to a free jet, and where robust along-shelf convergence brings cool, relatively fresh Middle Atlantic Bight and warm, salty South Atlantic Bight shelf waters together, forming an important and dynamic biogeographic boundar…

• Ocean Circulation Near Cape Hatteras: Observations of Mean and Variability

  Journal of Geophysical Research Oceans · 2022-11-20 · 8 citations

  articleOpen access

  Abstract The convergence of different water masses on the shelf and along the shelfbreak, and cross‐isobath shelf‐open ocean exchanges contribute to the complex circulation near Cape Hatteras. We examine the mean and variability of these circulations using data from nine bottom‐mounted acoustic Doppler current profilers, deployed over the mid‐ to outer‐continental shelf north and south of Cape Hatteras as part of the Processes driving Exchange At Cape Hatteras program. The 18‐month‐mean depth‐av…

• An Observation-Based Study of Gulf Stream Meander Kinematics Offshore of Cape Hatteras

  Frontiers in Marine Science · 2022-06-23 · 8 citations

  articleOpen access

  Gulf Stream (GS) meander structure and propagation offshore of Cape Hatteras are investigated by integrating current measurements from a bottom-moored Acoustic Doppler Current Profiler (ADCP) with high-frequency radar (HFR) surface current measurements and satellite Sea Surface Temperature (SST) images during November 2014. The ADCP measurements provide well-resolved current observations throughout most of the water column, while hourly surface current measurements from HF radars and available s…
