Thanks to humans, Salish Sea waters are too noisy for resident orcas to hunt successfully

University of Washington — Tue, 10 Sep 2024 11:05:17 EST

Scientists report that underwater noise pollution -- from both large and small vessels -- forces northern and southern resident orcas to expend more time and energy hunting for fish. The din also lowers the overall success of their hunting efforts. Noise from ships likely has an outsized impact on southern resident orca pods, which spend more time in areas with high ship traffic.

Aquatic invasive species are more widespread in Wisconsin than previously thought

University of Wisconsin-Madison — Thu, 05 Sep 2024 11:05:34 EST

A report on more than 40 years of research on Wisconsin lakes is highlighting some of the lessons scientists have learned about aquatic invasive species, including that far more ecosystems are playing host to non-native species than previously thought. However, the researchers note, those species aren't necessarily detrimental to their new habitat and, in some cases, the negative "impacts of invasive species control may be greater than the impacts of the invasive species" themselves.

SMU Researcher Helps Develop New Technique to Explore Oceanic Microbes

Southern Methodist University — Wed, 04 Sep 2024 14:05:04 EST

Alexander Chase and colleagues collect samples from Earth's oceans using SMIRC, which could be the first step in uncovering compounds that lead to next-generation antibiotics.

How a salt giant radically reshaped Mediterranean marine biodiversity

University of Vienna — Thu, 29 Aug 2024 14:00:00 EST

A new study paves the way to understanding biotic recovery after an ecological crisis in the Mediterranean Sea about 5.5 million years ago.

Marine engineering group to award ORNL researchers for innovative welding software

Oak Ridge National Laboratory — Wed, 28 Aug 2024 15:20:09 EST

Zhili Feng, a distinguished R&D staff member, and Jian Chen, a senior R&D staff member, in Materials Science and Technology Division at the Department of Energy's Oak Ridge National Laboratory, will receive the Elmer L. Hann Award at the Society of Naval Architects and Maritime Engineers, or SNAME, Convention on Oct.

Rain or Shine? How Rainfall Impacts Size of Sea Turtle Hatchlings

Florida Atlantic University — Wed, 28 Aug 2024 08:30:40 EST

An internationally collaborative study delves into how fluctuating rainfall impacts the development of sea turtle hatchlings, revealing that it has a more profound effect than changes in air temperature. Regional weather influences incubation and hatchling development and the impact of rainfall varies between species. For loggerhead turtles, heavier rainfall results in hatchlings with smaller carapaces (shell) but greater weight, while green turtle hatchlings grow smaller carapaces without a change in body mass.

MSU, DNR partner to protect lake sturgeons from extinction

Michigan State University — Fri, 23 Aug 2024 15:05:24 EST

Five hundred juvenile sturgeons were released into the Saginaw River system last week as part of an ongoing effort to bring the giant fish back from the brink of extinction.

Revealing the Secrets of Carbon from Ocean Waters: How Molecules Control Organic Matter Persistence from Surface Waters to the Depths

Environmental Molecular Sciences Laboratory - EMSL — Thu, 22 Aug 2024 12:05:58 EST

A study led by the University of Minnesota and the Environmental Molecular Sciences Laboratory sheds light on the origins and ultimate fate of organic carbon by resolving distinct components that cycle at different rates.

This research highlights the complex interactions between these microscopic pollutants and key aquatic producers, providing essential insights into the ecological impacts of nanomaterial pollution.

Fishing for missing environmental data in coastal oceans

University of Delaware — Wed, 21 Aug 2024 12:05:44 EST

A new University of Delaware study addresses the lack of data on how much human-generated carbon dioxide is present in coastal oceans - the saltwater ecosystems that link the land and sea. Capturing this data is crucial to calculating how much emissions must be cut in the future.
