Ocean Acoustics: Communicating with Instruments Sitting on the Seafloor

The bottom-mounted research instruments utilized by Processes Driving Exchange at Cape Hatteras (PEACH) scientists sit anywhere from 20 meters to more than 3000 meters beneath the surface of the ocean. These instruments measure the entire water column above using a variety of remote and in situ methods of data collection. With exception to 2 moorings utilizing surface-based meteorological instruments, there is no…

R/V Neil Armstrong Science Operations Begin

OOMG members Dr. Joe Zambon (Research Assistant Professor), Shun Mao (Ph.D. Student) and the rest of the multi-institutional Processes Driving Exchange at Cape Hatteras (PEACH) team arrived in their study region and science operations began. While the R/V Neil Armstrong has been recording important scientific data since leaving the dock in Woods Hole, MA, the first in situ measurements of the study…

Test Radiosonde Launch

Joe an dradiosonde balloon

OOMG member Dr. Joe Zambon tested a balloon-carried radiosonde with the help of NCSU’s Dr. Matt Parker from the roof of Jordan Hall. After filling the large balloon with helium, Joe and Matt zip-tied it closed, then attached the unwinder. Between the balloon and the radiosonde, the unwinder gently spools out 10 m of string so that the radiosonde is far enough…

Upcoming Gulf of Mexico Research Cruise Log Book Now Open

A research cruise in the Gulf of Mexico to support the project Three-Dimensional Gulf Circulation and Biogeochemical Processes Unveiled by State-of-the-Art Profiling Float Technology and Data Assimilative Ocean Models will take place May 1-10, 2017. University of Miami’s Rosenstiel School of Marine and Atmospheric  Science (RSMAS) is leading the expedition, aboard the R/V F. G. Walton Smith. UMiami Principal Investigator (PI) Nick Shay, NC State University…

Cruise Planning for the Final Push

Onboard the R/V Neil Armstrong, OOMG’s Joe Zambon and NCSU Marine Science undergrad Lauren Ball have been assisting with the NSF-funded Processes investigating Exchange Around Cape Hatteras (NSF-PEACH) project. A crucial component of the ongoing cruise is to utilize real-time in situ, satellite, and model data to assist Chief Scientist Magdalena Andres position the ship for crucial measurements while at sea. Joe…

Educational Outreach at Sea

Valerie Winzenried, a retired gifted-education teacher and an education consultant for Eastman, boarded the R/V Neil Armstrong last week. During her time at sea, she has been participating in hands-on research and data analysis along with onboard scientists. In addition, she has been interviewing researchers in order to construct lesson plans in geosciences to educate the next generation of oceanographers. She sat…

NSF-PEACH Cruise Halfway Completed

Last Saturday (22-April) marked the halfway point of the NSF-PEACH R/V Neil Armstrong cruise with OOMG’s Joe Zambon and NCSU Marine Science undergrad Lauren Ball. While underway at sea, both researchers have participated in research exploring the waters along the continental shelf from Cape Cod, MA to Cape Hatteras, NC. So far, the team has taken advantage of the prevailing calm seas…

Filling the Gaps with Models

Throughout the NSF-PEACH research cruise, OOMG’s Joe Zambon has been providing data to PIs and Chief Scientist Magdalena Andres for cruise planning. Several study sites were pre-determined months in advance, but this data has been instrumental in determining supplementary surveys of the Gulf Stream. In addition, short-duration features such as eddies have been sampled by determining their location while at sea. One…

Bathymetric Survey Off Cape Hatteras

One cruise objective for the April 2017 NSF-PEACH research cruise is to conduct a bathymetric survey of the shelf break approximately 20 nautical miles east-southeast of Cape Hatteras, NC. UNC’s Sara Haines explains that existing bathymetry in this area is of questionable quality possibly owing to the stitching of hand-drawn bathymetric maps in along the line of latitude at 35ºN. Over 2…

Cape Hatteras Research Cruise Continues

The cruise progresses, and the scientists have used calm weather days to work on instruments on moored buoys. Some deployed instruments are already returning data, showing the velocity of the Gulf Stream. Read details of the instruments being used at the UNC Coastal Studies Institute’s site here.
