CTDs Underway on the R/V Neil Armstrong

After the successful recovery and refurbishment of several bottom profilers, moorings, and surface buoys, the first transect of the PEACH (Processes Driving Exchange at Cape Hatteras; NSF Award: 1559476) cruise was undertaken this evening and into the early morning hours.  The transect spaced 7 stations along 60km of ocean from a few kilometers off of the NC Outer Banks to the continental shelf break.  To collect sub-surface data, scientists utilized shipboard CTD, the…

PEACH Cruise Underway

Dr. Joe Zambon and over a dozen scientists and PIs making up the PEACH (Processes Driving Exchange at Cape Hatteras; NSF Award #1559476) project departed the frozen waters of Woods Hole, MA on Monday morning (8-January) for Cape Hatteras onboard the R/V Neil Armstrong.  The first day of travel was difficult with high seas and crashing waves.  The anticipated transit time is 36 hours from Woods Hole, MA to…

Second PEACH Cruise Soon to be Underway

On Saturday, Dr. Joe Zambon arrived in New England to board the R/V Neil Armstrong for a journey down to offshore Cape Hatteras, NC.  The study is part of the PEACH, Processes Driving Exchange at Cape Hatteras, grant sponsored by NSF (Award: 1559476).  The next day will be spent mobilizing and retrofitting equipment onto the vessel for meteorological rawindsonde balloon deployments, a first…

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…

Hurricane Irma Siphons Water Away from West Florida Coast

An interesting phenomena has been observed in the wake of Hurricane Irma as it moves along the west Florida coastline.  Several images have been put on social media of water drastically receding away from the coastline, whereas tropical storms usually result in surge as they make landfall. This phenomenon is largely due to 2 factors.  First, the winds ahead of Irma are…

Irma Landfall Update, 8-Sept

Our coupled models, initialized at 8pm on September 7th, have completed and are now able to resolve Irma making landfall in Florida sometime between 2am and 5am Sunday morning.  As a result, both the 3 and 7 day runs are capable of resolving the storm and currently point the landfall as occurring between Miami and Homestead (where Andrew made landfall in August 1992)….

Irma 7-Day Forecast Updates (Sept 6 and 7)

Over the last few days, the 7-day forecast experiment upgrade has been working well.  Our output from forecasts initialized on the 6th and 7th are largely in line with the forecast models that the National Hurricane Center (NHC) has been favoring in their forecast tracks.  We have been utilizing additional resources provided by the High Performance Computing (HPC) center at NC State…

For Irma, the First Ever 7-Day CNAPS Forecast

Over the last few weeks, we have been working to expand the current CNAPS forecast from 3 to 7 days.  With the appearance of Hurricanes Harvey and Irma, and the peak of the hurricane season on September 10, we were graciously allocated additional computing power from the High Performance Computing (HPC) Center at North Carolina State University to perform some experimental simulations of…

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…
