PMEL's Ocean Molecular Ecology (OME) program uses 'Omics tools to tackle global ocean issues. We help lead the implementation of the NOAA 'Omics strategy and the National Aquatic eDNA Strategy to advance NOAA's mission of science and stewardship. We seek to leverage advances in molecular biology to scale biological analyses with physical and chemical processes. Our science aims to characterize the impacts of warming, ocean acidification, and hypoxia on marine life. This allows for characterization of marine ecosystems as they respond to a changing climate.

OME work directly supports NOAA's core missions in numerous ways

  • Understand and predict Earth systems by characterizing climate impacts on marine biodiversity.
  • Develop technology to improve NOAA science, service, and stewardship by advancing 'Omics approaches.
  • Transition results so they are useful to society - we do this by creating open access data dissemination, bioinformatic software, and genetic resources.
  • Provide stewardship and maintain sustainability of the Nation's living marine resources, their habitats, interactions, and ecosystems by generating critical biodiversity information that is foundational for climate resilient ecosystem based fisheries management.

Hi, I’m Brookelynn Gotschall, and this summer I had the opportunity to join NOAA PMEL’s Ocean Molecular Ecology Group as an undergraduate research intern under the NOAA Ernest F. Hollings Scholarship. My primary project focused on the urgent environmental challenge of Harmful Algal Blooms (HABs). As ocean temperatures rise, some microscopic algae known as phytoplankton rapidly multiply, causing blooms that release harmful toxins or physically harm animals and humans, making them HAB species. One such organism, Alexandrium catenella, produces lethal toxins responsible for paralytic shellfish poisoning, which can cause symptoms ranging from dizziness and vomiting to respiratory failure in humans. 

To better understand where these toxic blooms might strike next, I analyzed a... more
