Core Knowledge

During a recent trip to Alaska’s Kenai Peninsula, WHOI guest student Chris Maio assisted in the collection of sediment cores from the Beluga Slough salt marsh. The trip was funded by the U.S. Geological Survey and led by Ian Shennan from Durham University in England to gather cores to assess earthquake hazards and decipher local sea-level fluctuations. Salt marshes can also contain valuable records of tsunamis and storms that often stretch back centuries.(Photo by Christopher Maio, Woods Hole Oceanographic Institution)
