From The Field

North Carolina

April 8, 2020

BY EMILY GRIFFIN, NORTHEASTERN GUEST STUDENT On February 18, 2020, the Coast Systems Lab drove down to North Carolina to get sediment cores and find out more information about hurricanes that have occurred there in the past. The team included myself (Emily Griffin, a Guest Student), Ethan St. Aubin (another Guest Student), Mitchell Starr and…

Hurricane Michael

Hurricane Michael

Michael made landfall at Mexico Beach, Florida as a category 5 hurricane in October 2018. The storm resulted in 16 deaths and about $25 billion in damages. Two of our study sites, Shotgun and Mullet Pond, are located ~63 miles from Mexico Beach. We are interested to see if the hurricane would leave a deposit…

Glacial Lake Diagram

By: Simon Pendleton, WHOI Postdoctoral Scholar While September may be the end of the summer season in upstate New York lake country, it is prime time to go lake coring! Earlier this fall the CRL group took a break from marine excursions to pack up the coring equipment and head inland in search of glacial lake…

by Dana MacDonald The University of the West Indies (UWI) – Mona Campus Kingston Jamaica hosted a two-day workshop on identifying and analyzing macro-charcoal from sediments to characterize past fire regimes on May 3rd and 4th, 2017. Two days were devoted to exploring techniques and research tools from past efforts to reconstruct paleo-fires in New…

In The Trenches

Stephanie Madsen and Aleja Ortiz note stratigraphic changes on Eneko Island in the central Pacific.

Stephanie Madsen and Aleja Ortiz note stratigraphic changes on Eneko Island in the central Pacific. Sure, acoustic sub-surface imagery and ground penetrating radar are great. Resistivity sensors and magnetometers can tell us so much. We can learn a lot from X-Ray Diffraction scans and radiography. But often the best way to understand the Earth beneath…

A Family Affair

Jeff and his father arrive in Good News Bay

Whether exploring remote wilds, asking questions in our own backyards, or helping out in the lab you’ll find the Donnelly’s are hard at work. In 2010 Jeff Donnelly’s father, Pat, was fortunate enough to accompany the team to Good News Bay in Alaska as part of a project investigating high latitude barrier beach development Jeff…

Unalaskan Rodeo

May 13, 2015

The problem, in the deep and narrow confines of Naginak Bay on Unalaska Island in the Aelutians, was that the anchors kept slipping. A successful coring operation requires that the coring platform stays still and does not drift off station. While high-tech solutions such as dynamic positioning can be used on larger and more expensively…

Everything Should Be Waterproof

April 27, 2015

On a recent field expedition to the remote western end of Kwajalein Atoll in the central Pacific, the team encountered a different sort of problem than what they’re used to.  There was no safe place for the boat to land.  The shallow reef flat and heavy surf prevented the 50′ boat supplied by the US…

Hole in One

April 10, 2015

WHOI geologist Jeff Donnelly and research assistant Richard Sullivan recently joined Texas A&M University at Galveston (TAMUG) geologist Pete van Hengstum and undergraduate student Tyler Winkler in collecting cores from Thatchpoint Bluehole. It is thought that blueholes form when rising seas flood a sinkhole, formed when limestone bedrock is dissolved from below by groundwater and collapses. The team collected…
