Scientists from the USGS Woods Hole Coastal and Marine Science Center and Woods Hole Oceanographic Institution (WHOI) conducted near-shore bathymetric surveys on Cape Cod National Seashore. Bathymetry is the study of underwater depth of ocean floors or lake floors. By collecting data and plotting points on our beaches with cameras, survey equipment, and even a surf-capable autonomous surface vessel (ASV), scientists can learn more about the dynamic processes shaping our coasts. The knowledge gained from this research will improve computer-derived simulations of coastal flooding and shoreline change that communities can use to identify hazards in areas vulnerable to storms, chronic erosion, and sea-level rise.

Winter temperature extremes control the distributions of subtropical fishes. Common snook (Centropomus undecimalis), aggregate at a spring in northern Florida during winter. Snook are warm saltwater game fish, common in Florida, that have been moving further northward as extreme cold spells become less frequent and less intense.
