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…

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…

Undergrad Perspectives on a Research Cruise: Part 2

By Lauren Ball, a senior in the Dept. of Marine, Earth, and Atmospheric Sciences at NC State University. Lauren is part of the science crew on the R/V Neil Armstrong, collecting data off of Cape Hatteras, NC. One thing I was not expecting about this research cruise was the lack of a personal schedule.  I am on watch from midnight to noon,…

Undergrad Perspectives on a Research Cruise: Part 1

By Lauren Ball, a senior in the Dept. of Marine, Earth, and Atmospheric Sciences at NC State University. As a graduating senior in Biological Oceanography, I am very fortunate to have the opportunity to participate in the PEACH Cruise on the R/V Neil Armstrong.  I ended up only having one class this semester, Observational Methods and Data Analysis in Marine Physics, and…
