In the winter of 2015, the public noticed thousands of dead seabirds washing ashore across the western coast of the United States and Canada. The USGS linked this massive seabird die-off to the North Pacific Marine Heatwave. A marine heatwave occurs when sea surface temperatures are above normal for an extended period of time.

The ocean is home to a wealth of biodiversity - from invisible-to-the-eye microbes to the larger-than-life megafauna - and unique marine habitat, such as deepwater coral reefs, seamounts, and submarine canyons. USGS science helps inform the management and conservation of marine biodiversity and habitats, from the coastlines down to the deepest trench.
Life in the Sea
From the microscopic plants known as phytoplankton that form the basis of the aquatic food web to the largest animal to ever live on Earth, the blue whale, our oceans are home to a wealth of biodiversity and every organism plays a critical role in the structure and function of this expansive marine environment.
Sources/Usage: Public Domain. View Media Details
Maintaining this biodiversity is important because a healthy ocean provides us with oxygen, helps regulate climate and weather, acts as a source of protein for many people around the world, and provides jobs and opportunities for eco-tourism and recreation. USGS science informs the management and conservation of marine biodiversity and habitats, in both nearshore and deepwater ecosystems.
USGS Role in Marine Ecosystems Research
From the Atlantic to the Pacific and the Gulf Region in between, USGS scientists have implemented a multi-faceted offshore research program that weaves together expertise in a variety of disciplines to investigate nearshore and deepwater ecosystems. This interdisciplinary approach relies on a network of partners from around the Nation and the world to examine microbiology, population genetics, paleoecology, food webs, taxonomy, community ecology, physical oceanography, seafloor characteristics, and submarine hazards in the little explored, yet vital, marine ecosystems.

Wildlife disease: Much like terrestrial species, animals in the ocean have to worry about the spread of disease. USGS scientists across the Nation are working together with various federal and state partners to assess and better understand a novel coral disease that first appeared in stony corals off the coast of Florida in 2014 and has now spread throughout the Caribbean. In Hawaii, USGS scientists are studying the cause and spread of fibropapillomatosis, a disease that leads to tumors growing internally and externally on sea turtles.

Wildlife tracking: Understanding the short- and long-distance movements of wildlife, particularly those species that spend most of their life offshore and/or underwater, is critical for a wide variety of ecological research questions and management decisions. The USGS tags and tracks imperiled marine species, such as sea otters, sea turtles, and seabirds to learn about their behavior, migration patterns, and habitat use and areas of high use. This information can help inform the creation of marine protected areas or the development of species management strategies. Several aquatic animals, such as manatees or fishes like Chinook salmon and river herring, can move between fresh and salt water. Tracking their movement can reveal connections between marine and coastal ecosystems and provide insight into the seasonality of mass migrations.

USGS Science in Nearshore Ecosystems
Nearshore systems are the habitats in which most people interact with marine environments, which include seabirds, seagrasses, algae, benthic invertebrates and fish, and top predators that include marine mammals like sharks, sea otters, walruses, and even polar bears. USGS research addresses natural and human-induced changes to this ecosystem and all its components.

Exploring Deep-sea Ecosystems
Most life in the ocean exists in surface waters above 200 meters depth where they have access to sunlight. However, even below 200 meters, where little to no sunlight reaches, temperatures drop, and pressure increases, abundant life exists. A diversity of organisms, including fishes, crustaceans, cephalopods, anemones, sea stars, microbes, and even corals make their home in the deep sea. These organisms reside on topographically complex terrain mirroring our terrestrial landscape, dotted with features like trenches, seamounts, canyons, and volcanoes. They also leave behind fossils that help geoscientists construct models of ancient ocean conditions and Earth’s geologic history, as shown in the schematic below.

Life at the Bottom of the Ocean
The mention of the seafloor may evoke thoughts of a deep, dark expanse of nothing, but the often-assumed void of life in the deep sea couldn’t be further from the truth. Even with the lack of sunlight, an average temperature of 4 degrees Celsius, and extreme pressures that an unprotected human could not survive, the deep sea is brimming with biodiversity, including deep-sea corals. The DISCOVRE (DIversity, Systematics and COnnectivity of Vulnerable Reef Ecosystems) program investigates unique and fragile deep-sea coral environments from the microscopic level to the ecosystem level. The multi-disciplinary approach has enhanced our understanding of the structure and function of significant biological communities surrounding deep coral reefs off the United States’ coasts.
