Characterizing salps as predators of marine microbes

Salps are found to control microbial community structure and function by capturing a variety of microbe types, including Prochlorococcus. The study reveals that simple mechanical principles do not explain cell capture by salps, indicating a complex mechanism at play.

Converging ocean currents bring floating life and garbage together

A community science survey reveals an abundance of floating sea creatures in the North Pacific Garbage Patch, including jellyfish, snails, and crustaceans. The study found a positive correlation between plastic waste and three groups of sea creatures, highlighting the complex relationships within this ecosystem.

Study identifies new cause of melting Antarctic ice shelves

Researchers have found that a weak ocean gyre near the Thwaites Ice Shelf allows more warm water to access its base, causing it to melt. This process is driven by waters from nearby melting ice shelves and can impact the stability of adjacent ice shelves, contributing to global sea-level rise.

How do microplastic particles differ across the Atlantic Ocean?

A new study published in Marine Pollution Bulletin found significantly higher levels of polyethylene, polypropylene, acrylic, and polyamide in the North Atlantic gyre compared to other offshore locations. Inshore areas exhibited a diverse range of polymers, possibly influenced by proximity to various plastic sources.

Small eddies play a big role in feeding ocean microbes

Researchers have discovered that small eddies, swirling at the edges of massive ocean currents, are a key source of nutrients for phytoplankton. These nutrient-rich eddies help maintain healthy populations of phytoplankton, which are essential for carbon sequestration and mitigating climate change effects.

Arctic ice sets speed limit for major ocean current

The Beaufort Gyre's speed is controlled by the Arctic ice cover, which acts as a natural governor to slow down the gyre. As the Arctic ice melts, the gyre speeds up, gathering more fresh water from the Arctic's river runoff and melting ice.

Gulf Stream eddies as a source of iron

Researchers from ETH Zurich have found that cold, iron-rich seawater from the North American continental slope is captured by meanders of the Gulf Stream and carried out to the North Atlantic Gyre, enriching it with iron. The study suggests that this source may deliver up to 15% of the iron delivered by Saharan dust.

Tracking sea turtles across hundreds of miles of open ocean

Researchers document leatherback sea turtles' ability to maintain specific headings while traveling through the subtropical gyre, unaffected by current drift. The study suggests that turtles may use a magnetic and/or solar compass to navigate.

URI oceanographer to lead return visit to least inhabited place on Earth

A team of scientists, led by URI oceanography professor Steven D'Hondt, will embark on a nine-week expedition to the South Pacific Gyre to drill into the basaltic basement and search for evidence of life. The team aims to test whether microbial communities can be sustained by hydrogen released from radioactive water decay.

Ocean's color affects hurricane paths

A study found that a decrease in chlorophyll concentration, leading to a change in ocean color, can reduce hurricane formation by 70% in the North Pacific. This reduction is due to changes in air circulation patterns and surface water temperature.

Mapping nutrient distributions over the Atlantic Ocean

Researchers have mapped the large-scale distributions of dissolved organic nitrogen and phosphorus over the Atlantic Ocean, finding that these nutrients dominate surface waters and play a crucial role in export production. The study suggests that nutrient-poor regions, like subtropical gyres, rely on these nutrients to sustain life.

Subseafloor sediment in South Pacific Gyre

A team of scientists found surprisingly few organisms beneath the seafloor of the South Pacific Gyre, with cell counts three to four orders of magnitude lower than at similar depths outside gyres. The sediment's oxygen levels were also unexpectedly high, supporting an aerobic community.

Climate: New spin on ocean's role

Researchers found massive swirling structures called gyres in the Southern Ocean, trapping pollutants and nutrients. These features play a crucial role in pumping heat poleward, moderating the planet's extremes in climate.

Leatherback turtles' newly discovered migration route may be roadmap to salvation

A study tracking leatherback turtles in the eastern Pacific Ocean has revealed a narrow corridor they consistently follow, potentially leading to fishing suspension and improved management. The turtles' movements are correlated with environmental features and fishing activity, providing new opportunities for conservation efforts.

NASA satellite sees ocean plants increase, coasts greening

Phytoplankton amounts have increased globally by over 4% along coastal regions, while declines were observed in mid-ocean gyres. This shift may indicate changes in the biology of oceans, particularly in coast regions, and has implications for ocean ecosystems and climate change.

Satellites record weakening North Atlantic current

The subpolar gyre's weakening trend is attributed to heat exchanges from the ocean to the atmosphere playing a bigger role. This study, published on Science Express Web site, found Labrador Sea water warmed during the 1990s, reducing contrast with warmer southern latitudes and driving ocean circulation.
