Lamont’s Linda Heusser turned 90 years old on April 12, and the only birthday present she really wanted was another sediment core to study.
The expedition discovered stresses along an underwater plate boundary and a record of historic and pre-historic earthquakes, which will shed light on the geohazard risks for Jamaica and Haiti.
Researchers studying earthquake hazards in the Caribbean faced several challenges at sea, from rough weather to equipment failures.
Motion along these faults is associated with the 1907 Kingston earthquake, which shook the capital of the island with a magnitude of 6.2
Despite all the “Waiting on Weather” and “Running Away from Weather,” the expedition recovered exciting new sedimentary climate records in the remote and notoriously stormy Southern Ocean.
Recovering ancient seafloor sediments requires complicated machinery and a skilled crew.
A scientist explains how she lines up wiggles on a screen to recover the missing layers in cores drilled from the bottom of the ocean.
It took six days to sail to Point Nemo, the most inaccessible point of the ocean on this planet, to drill a sample from the ocean floor.
