Tyler Barnes is a graduate student in the Geological Oceanography Lab at MLML. His curiosity in in coastal processes was sparked as an undergraduate at the University of San Diego where he joined a research lab investigating sedimentation in bays with coral reefs in St. John, USVI. Soon after, Tyler began his master’s degree in which his research assesses geomorphologic change on beaches in Monterey Bay using a terrestrial laser scanner (ground-based LiDAR that creates 3-D models of surveyed surfaces). Simultaneously, Tyler has worked as a researcher for Central Coast Wetlands Group where he has assisted on projects monitoring bar-built estuary hydrology/ecology throughout California and completed topographic surveys for restoration projects.
Dr. Patricia Eichler is Biological Oceanographer interested on the assessment of coastal and marine environments through the use of marine benthic Foraminifera, physical and geo-chemical datasets. More recently, she has been focusing on the use of stable isotopes for micropaleontology studies and paleoenvironmental reconstruction. Her skills and expertise focus in the Environment, Water Quality, Ecology and Evolution, Ecosystem Ecology, Marine Ecology, Sedimentology, Biodiversity, and Conservation of Marine Environment and Marine Biodiversity. She is a Professor at the Environmental Sciences Post Graduation Program at Sul de Santa Catarina University (Unisul) and at the Geodynamic and Geophysics and Geophysics Post Graduation Program in the Federal do Rio Grande do Norte University.
Welcome to MLML, Dr. Eichler!
Dorota Szuta is a Master’s student under the guidance of Dr. Stacy Kim of the Benthic Ecology lab and Dr. Ivano Aiello of the Geological Oceanography lab. She earned her BS degree in Marine Biology at UC Santa Cruz in 2009. After her undergraduate work, she worked in the Benthic Ecology lab as a field diver and lab tech for two years. In her free time, she likes to play music, make art, and pet dogs. Her Master's thesis focuses on communities of benthic invertebrates under ice in Antarctica.
The Ross Sea, Antarctica is a deep bay of the Southern Ocean that exhibits seasonal sea ice and is adjacent to a permanent ice shelf overlying seawater. Though the shallow-water seafloor communities in the Ross Sea are known to be high in species richness and abundance, the deeper sublittoral zone (approximately 25 m – 200 m) has been generally understudied and, especially under the Ross Ice Shelf, the benthic community composition is largely unknown. In 2008 and 2009, imagery of the seafloor at two sites under the permanent Ross Ice Shelf and two sites under the seasonal ice in the Ross Sea was collected via remotely operated vehicle (ROV) at depths to 300 m. Several patterns in Antarctic benthic communities were seen over multiple environmental gradients. Species abundance typically exhibited a unimodal distribution with depth, reflecting a food limitation at the deep end and potentially ice disturbance on the shallow end. Diversity and depth had quadratic relationship at two of three sites encompassing a depth gradient. In terms of functional groups, the proportion of suspension feeders decreased with depth at one site, and no pattern was found at other sites. The group sessile predators, comprised of several species of anemones, increased with depth proportionally, suggesting that they use a range of feeding strategies to adapt to life at depth. Benthic communities under seasonal ice were different than those under permanent ice shelves, with higher overall species diversity, a greater proportion of suspension feeders, and a degree of magnitude higher abundance.
