2020年12月1日 · Marine mammals are warm-blooded vertebrates (animals with a backbone) that bear live young and nourish them with milk as land mammals do, but that spend most or all of their lives in the ocean. They are broken into three groups that share similar adaptations to their aquatic life, but that have very different origins and life patterns.

2021年6月3日 · Plastics could present a risk to both marine animals and humans since they may contain toxic chemicals like phthalates, bisphenol A and others used in the manufacturing process. These additives can change the properties of plastic items in different ways. For example, they may make water bottles more rigid, and pens more flexible.

2025年1月23日 · As filter feeders, they often grow from high vantage points to skim nearby currents for tasty particles and swarming zooplankton. In Stellwagen Bank National Marine Sanctuary, New England, WHOI biologists have recorded more-concentrated populations of these animals along shipwrecks than on other native substrates like boulder reefs.

2024年5月24日 · In 1977, scientists discovered hydrothermal vents. These seafloor hot springs release mineral-rich water that attracts an abundance of life, including shrimp, crabs, and six-foot-tall tubeworms.

2021年2月25日 · Researchers have been collecting samples and studying the abyssal seafloor since the 1960s and have discovered a surprising diversity of life at these depths. Entire communities of animals and microbes adapted to the high-pressure environment thrive in the dark depths, relying on limited carbon input from land or whale falls.

2013年5月2日 · Fisher, a marine biogeochemist at Stony Brook University, has spent 35 years studying the fate of metals and radioisotopes in marine organisms, including radioisotopes associated with nuclear waste. He and members of his lab participated in the research cruise led by Woods Hole Oceanographic Institution marine geochemist Ken Buesseler off the ...

2004年9月15日 · They become available as food for higher organisms in the food web, the zooplankton—tiny marine animals that, in turn, are eaten by larger animals, from fish to jellyfish to whales. A rich and vulnerable ecosystem. Nowhere is the plankton ecosystem less well-understood than in the Arctic Ocean.

2021年10月7日 · In Paleozoic seas, non-skeletal corals frequently grew on the bodies of marine animals called sea crinoids, or sea lilies--a flowery relative of the starfish. Though the seafloor is rich with their fossils, the pair seemed to disappear from the fossil record around 273 million years ago and was believed to have gone extinct.

2021年2月9日 · These “marine calcifiers” face two potential threats associated with ocean acidification: 1) Their shells and skeletons may dissolve more readily as ocean pH decreases and seawater becomes more corrosive; and 2) When CO 2 dissolves in seawater, the water chemistry changes such that fewer carbonate ions, the primary building blocks for ...

Bioadhesive Interface for Marine Sensors (BIMS) can be attached to marine animals in less than 20 seconds. Traditional tagging methods could take up to ten minutes, causing stress to animals, making these a better alternative. Here, Dr. Pedro Alfono places a tagged squid back in the water in the Azores after using a traditional suture tag.
