Examining Cetaceans for Contamination and Pathogens
CSS has employee owners who are experts in monitoring cetacean health. Several CSS scientists supporting NOAA’s Centers for Coastal Ocean Science have recently conducted research and tests on marine mammals to explore uncommon behaviors and causes for strandings. View some examples of this research below.
Microplastics are becoming increasingly abundant in coastal and marine environments. A CSS marine mammal microplastics specialist is monitoring microplastic abundance and types in the gastrointestinal tracts of stranded cetaceans. Since 2022 our specialist has processed over one kilometer of intestines from 53 marine mammals, most of which have been Tamanend’s bottlenose dolphins (Tursiops erebennus) local to the Charleston Harbor Estuary. Our specialist has discovered microplastics in every marine mammal tested to date, with the most common plastic being polypropylene fibers, a plastic commonly used in fishing nets, construction materials, textiles, and other synthetic products.
CSS scientists are using unoccupied aerial systems (UAS), also known as drones, to collect blow exhalation samples from Tamanend’s bottlenose dolphins in the Charleston Harbor Estuary. Over the past 20 years, these dolphins have been observed moving from waters with higher salinity to waters with low salinity, often needing rescuing and displaying poor health conditions. Using a UAS equipped with petri dishes enables scientists to monitor the respiratory health of dolphins at low cost in a non-invasive manner. Through these collections, CSS scientists are screening samples for respiratory pathogens and have screened more than 40 samples to date.
When the South Carolina Department of Natural Resources discovered a beached 43 ft sperm whale in Bulls Bay along the South Carolina coast, CSS cetacean specialists jumped to action. They assisted the Lowcountry Marine Mammal Network with the field response and partial necropsy by transporting supplies to the site, taking measurements, recording data, and collecting samples to understand what may have caused the death of this animal. The team examined the whale’s stomach and intestines for potential plastic ingestion.Throughout the examination, the team did not discover (macro)plastics within the cetacean’s digestive tract.

Training the Next Generation of Researchers
CSS staff support the National Institutes of Health (NIH) Division of Occupational Safety and Health by providing Safe Techniques Advance Research Science (STARS) training to summer interns. Following a pause during the pandemic, staff resumed training May 15, 2024. During the in-person STARS training, CSS staff cover key concepts from the pre-requisite NIH Lab Safety…
Custom Support to Space Florida
Our team recently reconfigured the office space and network for an incoming Space Life Science Lab tenant, Vaxxinity. This work included major renovations to the lab and office space, and new cable runs for their modified space. The team completed this large task within a four week period!
