Palaeontological signatures of the Anthropocene are distinct from those of previous epochs
The “Great Acceleration” beginning in the mid-20th century provides the causal mechanism of the Anthropocene, which has been proposed as a new epoch of geological time beginning in 1952 CE. Here we identify key parameters and their diagnostic palaeontological signals of the Anthropocene, including the rapid breakdown of discrete biogeographical ranges for marine and terrestrial species, rapid chan
Seasonality of retreat rate of a wave-exposed marsh edge
Wave-driven erosion of marsh boundaries is a major cause of marsh loss, but little research has captured the effect of seasonal differences on marsh-edge retreat rates to illuminate temporal patterns of when the majority of this erosion is occurring. Using five surface models captured over a study year of a marsh with a steep escarped boundary in South San Francisco Bay, we find a pronounced seaso
Invertebrate trophic structure on marine ferromanganese and phosphorite hardgrounds
The Southern California Borderland hosts a variety of geologic and oceanographic features that allow for diverse habitats to occur in a restricted region with a strong oxygen minimum zone (OMZ) and hard substrates. These include ferromanganese (FeMn) crusts and phosphorites targeted for deep-seabed mining in other regions. Baseline studies regarding hardground macro- (> 0.3 mm) and megafaunal (> 2

Eyes on Earth Episode 120 – Mapping the California Coastline
Coastline erosion can change your favorite beach. But it can also affect highways and buildings. Landsat, along with high-resolution data, can be used to model the past and predict the future of changes caused by sea level rise and coastal erosion.
Post-Fire Sediment Research at the Pacific Coastal and Marine Science Center
The USGS Pacific Coastal and Marine Science Center (PCMSC) in Santa Cruz, California, has been growing our post-fire research contributions since 2017, through studies of post-fire sediment movement that address the Natural Hazards Mission Area objectives for understanding wildfire hazards.
Anthropogenic Nutrient Loading and Coral Health at Ofu, American Samoa
Declining water quality poses a significant and persistent threat to coral reefs worldwide, contributing to their widespread degradation. Identifying the specific impacts of water quality stressors is challenging due to the complex interplay of various physical and biological factors affecting reef health. Submarine groundwater discharge (SGD) plays a crucial role in transporting nutrients into...
