USGS scientists share brief thoughts about why they have focused their careers on studying our oceans and coasts. Here’s why they study the ocean:

Jill is a biologist with the USGS Wetland and Aquatic Research Center, she says “I am fascinated by the ocean because there are still so many unique animals to be discovered. They are a source for the imagination, and I feel very fortunate to be a part of broadening our understanding of both known and unknown habitats.”Learn about Jill's Benthic Ecology Research.

Ilsa Kuffner is a Research Marine Biologist with the USGS St. Petersburg Coastal and Marine Science Center. Ilsa says, “The ocean covers 71% of Earth’s surface. While only 15% of Earth’s species live in the ocean, one out of four of them lives on a coral reef! But, like many ecosystems on land, coral reefs are an ecosystem in crisis—and they need our help. I study coral reefs to help provide knowledge humans need to make decisions on how best to manage and restore these critical natural resources. Coastal communities throughout the tropics are safer and more economically prosperous with healthy coral reefs than without them.”Visit the USGS Coral Reef Ecosystems Studies (CREST) website for more information.

Jennie McClain-Counts is a biologist with the USGS Wetland and Aquatic Research Center. She is fascinated by the ocean because, “there is still SO MUCH to explore and so many unknowns. During every offshore expedition there is something new to discover or experience. Whether it is whale falls, shipwrecks, bubbling seeps, mussel beds, or expansive deep-sea coral reefs, it’s a constant learning process to try and understand the relationships between animals and habitats. The more we explore, the more we discover how much we don’t know.” Here Jennie examines a sediment push core collected during a deep-sea expedition.Learn about Jennie's Benthic Ecology Research.

Jin-Si Over is a Geographer with the USGS Woods Hole Coastal and Marine Science Center. So, why does she love the ocean? "I love the ocean because without it we wouldn't have the amazing beaches I study and work on. Beaches host nesting grounds for piping plover, sea turtles, and are such a dynamic interface between the oceans and our own homes." Jin-Si works on coastal hazard assessments and forecasts from hurricanes to improve hurricane impact models for coastlines and coastal vulnerability to future storms as well as aid in post-storm recovery efforts.

Julie Richey, Ph.D. leads paleoclimate research at the USGS St. Petersburg Coastal and Marine Science Center. Julie loves studying the ocean and the privilege of doing work to contribute to our collective understanding of global climate change, an issue that not only she finds important, but that has broad-reaching societal implications. Here Julie is aboard the R/V Pelican.

Dr. Kimberly Yates is a Research Oceanographer with the USGS St. Petersburg Coastal and Marine Science Center. She has been studying ocean acidification for more than 20 years. Kim specializes in carbonate geochemistry and biogeochemistry. She’s a member of the Interagency Working Group on Ocean Acidification, Chair of the Gulf of Mexico Coastal Acidification Network, and a member of the Southeast Ocean and Coastal Acidification Network. When asked why she studies the ocean, Kim states, “I can’t remember ever considering any career other than science. My parents taught me an appreciation of nature and conservation through a very active life of outdoor recreation, especially on the water. I developed an insatiable curiosity about how nature works, and my favorite place was anywhere on or near the ocean. I couldn’t decide whether I wanted to pursue a college degree in biology, chemistry, or physics. I discovered that by choosing a career in the earth sciences, I could have a career in all three.”

Penny McCowen, a biologist with the USGS Wetland and Aquatic Research Center is fascinated by the ocean because, “it contains most of the life on earth, and marine phytoplankton produce the majority of oxygen in the atmosphere. We are so dependent on the health of our oceans, yet we know so little about them. Since such a small proportion of the ocean has been explored, the possibility for amazing discoveries is infinite.” Here Penny prepares vials for seafloor creatures collected during a deep-sea expedition in 2019.
