Planting the Seeds of Inspiration: Eelgrass Restoration

and planted the seeds of inspiration.”Quite literally this is what happened. In 2015, Vasiluth created an innovative and unique method for planting eelgrass seeds (Zostera marina) in Long Island, New York’s waters that’s helping to revitalize the dying eelgrass population, improve the marine ecosystem, and mitigate climate change.Long Island is a peninsula that stretches out from New York City into the Atlantic Ocean. The waters around Long Island include the Great South Bay in the south and the Long Island Sound in the north.In the past century, these waters have lost nearly 90 percent

DP World Introduces South Korea Seagrass Restoration Initiative

DP World has launched its first global seagrass restoration initiative on Geoje Island in South Korea, supporting efforts to restore 2.4 hectares of coastal marine habitat over the next four years and enhancing marine biodiversity. The initiative in South Korea was formalized through a Memorandum of Understanding (MOU) between DP World, Korea Green Foundation and the Korea Fisheries Resources Agency (FIRA). The MOU establishes a long-term collaboration focused on ongoing monitoring of seagrass meadows, the development of restoration approaches informed by scientific research, and continued

PML: 20 Years of Data Shows Declining Ocean Productivity Around UK

A new study by scientists at Plymouth Marine Laboratory (PML) has revealed a significant long-term decline in ocean productivity across large parts of the north-east Atlantic. This raises concerns about the future health of marine food webs, fisheries and the ocean’s ability to absorb and sequester carbon dioxide.Using more than two decades of satellite observations, researchers analyzed changes in microalgae net primary production, the process by which microscopic marine plants convert sunlight and carbon dioxide into organic matter, which forms the foundation of marine ecosystems.The study

SAMS Oceanographic Array Will Aid Atlantic Meridional Overturning Circulation Observations

Marine scientists in Scotland have helped to develop the most comprehensive view yet of how large-scale north Atlantic currents that dictate our climate may be changing.The scientists at the Scottish Association for Marine Science (SAMS) in Oban, a partner of UHI, have combined data from a range of sources to measure the mass formation of Atlantic currents, known as the Atlantic Meridional Overturning Circulation (AMOC).Their Scotland-Canada Overturning Array (SCOTIA) of observations incorporates data from scientific moorings on the existing sub-polar OSNAP array and the 50-year Extended Ellett Line

Project CETI Tracks Sperm Whale Conversations in Real Time

whales use clicks to navigate and hunt, and also produce patterned sequences of clicks, known as "codas," that are thought to play a role in communication. Scientists first identified that sperm whales vocalize in 1957. But understanding how they communicate has remained difficult because these marine mammals dive to depths of more than 1.6 km (one mile) for around 50 minutes each hour, making continuous observation challenging."The underwater glider is listening for whales via four hydrophones and then steering itself toward them using a feature called backseat driver," said David Gruber

Puntacana Foundation Launches Coral Restoration Farm in Dominican Republic

The Puntacana Foundation inaugurated the Marine Innovation Center (CIM), a new facility designed to promote research, environmental education, and the restoration of coral reef ecosystems throughout the Caribbean. Located in Playa Blanca, within the Puntacana Resort, on one of the country's most iconic coastlines, the CIM represents the next step in a conservation commitment that began more than thirty years ago.The inauguration, held in conjunction with Earth Day on April 22, 2026, brought together partners from the environmental, business, and philanthropic sectors, including the Puntacana Group

Brazilian Abrolhos Corals Decline as Climate Warms

Coral cover of Brazil’s Abrolhos reefs, the most biodiverse coral ecosystem in the South Atlantic, has fallen by around 15% over 18 years due to climate change and human activity, researchers in Rio de Janeiro told Reuters.Marine heatwaves linked to climate change have intensified so-called bleaching events where corals expel the algae that call them home, which permanently undermines coral health, said Rodrigo Leao de Moura, a marine biologist at the Federal University of Rio de Janeiro.“With the increasing frequency of heatwaves, corals may regain their color, but they develop necrosis

North Atlantic Right Whales Produce Highest Number of Births This Calving Season Since 2009

The North Atlantic right whale calving season has come to a close with the highest number of calves recorded since 2009.The annual calving season in the southeastern United States, which runs from mid-November until mid-April, produced 23 mother-calf pairs, the fourth-highest count ever. It’s positive news for the critically endangered species with an estimated population of about 380.Scientists with the Anderson Cabot Center for Ocean Life at the New England Aquarium have been tracking the season closely and were pleased to see shorter intervals between calving for the majority of the
