Nanoplastics negatively affect aquatic animals

Nanoplastics negatively affect aquatic animals | Marine Conservation Research | Scoop.it
Plastic accounts for nearly eighty per cent of all waste found in our oceans, gradually breaking down into smaller and smaller particles. New research investigates how nanosized plastic particles affect aquatic animals in different parts of the food chain.

Antarctic bryozoans give hints of environmental changes in oceans

Antarctic bryozoans give hints of environmental changes in oceans | Marine Conservation Research | Scoop.it
Antarctic regions are natural laboratories to study biodiversity and the impact of climate change. In Antarctica, some marine ecosystems are particularly vulnerable to the ocean acidification due to an excess of carbon dioxide released into the atmosphere. Studying the Antarctic bryozoans, marine invertebrates that live in colonies and make mineralized skeletons, can create new views to understand the effects of global ocean acidification.

Ocean currents push phytoplankton, and pollution, around the globe faster than thought

Ocean currents push phytoplankton, and pollution, around the globe faster than thought | Marine Conservation Research | Scoop.it
Ocean currents can carry objects to almost any place on the globe in less than a decade, faster than previously thought. While good for microorganisms such as phytoplankton that are essential to the marine food web, it also means that plastic debris, radioactive particles and virtually any kind of litter can quickly become a problem in areas far from where they originated.
Gaye Rosier's insight:
The oceans are all one and the whole world has to agree a plan to save them - and ourselves!

New imaging technique reveals vulnerability of coral reefs

New imaging technique reveals vulnerability of coral reefs | Marine Conservation Research | Scoop.it
Researchers have created a novel method using micro-computed tomography scans to expose how bioerosion and secondary accretion of corals -- critical processes for reef sustainability -- respond to varying environmental conditions, including changing ocean acidity.
Gaye Rosier's insight:
Useful research sheds light on how reefs are coping, or not, with ocean acidification.

All plastics should be made this way. If it costs more, we'll learn to use less. Many island nations are heavily dependent on nutrition from the sea whilst the "civilized " West uses the sea as a garbage dump and chokes the life out of it!

New research helps solve the riddle of the ocean carbon conundrum: About a quarter of the carbon dioxide we release each year ends up in the ocean, but how it happens is still not fully understood

New research helps solve the riddle of the ocean carbon conundrum: About a quarter of the carbon dioxide we release each year ends up in the ocean, but how it happens is still not fully understood | Marine Conservation Research | Scoop.it
Initially, the fact that the oceans are absorbing a significant amount of the carbon dioxide we pump into the atmosphere by burning biomass and fossil fuels would appear to be a good thing. However, as more carbon dioxide dissolves into the oceans, it changes the pH of the seawater (a process called ocean acidification), making it difficult for some marine life to survive.
Gaye Rosier's insight:
The seas around Europe absorb 24 million tonnes of carbon each year!

Bachelor's paradise: Female turtles outnumbering males due to warming temps: Climate change posing long-term stability challenges for turtles

Bachelor's paradise: Female turtles outnumbering males due to warming temps: Climate change posing long-term stability challenges for turtles | Marine Conservation Research | Scoop.it
Rising global temperatures may skew gender imbalance among the marine turtle population, according to new research. The sex of marine hatchlings is influenced by incubating temperatures, and warmer temperatures produce a higher number of female hatchlings.
Gaye Rosier's insight:

This population skew due to climate change could impact turtle survival.

Faster way to assess ocean ecosystem health

Faster way to assess ocean ecosystem health | Marine Conservation Research | Scoop.it
A new study identifies a set of features common to all ocean ecosystems that provide a visual diagnosis of the health of the underwater environment coastal communities rely on. Together, the features detail cumulative effects of threats -- such as overfishing, pollution, and invasive species -- so responders can act quickly to increase ocean resiliency and sustainability.
Gaye Rosier's insight:

A joined-up approach to marine health assessments.

Declines in whales, fish, seabirds and large animals disrupt Earth's nutrient cycle

Declines in whales, fish, seabirds and large animals disrupt Earth's nutrient cycle | Marine Conservation Research | Scoop.it
In the past, whales, giant land mammals, and other animals played a vital role in keeping the planet fertile by transporting nutrients via their feces. However, massive declines and extinctions of many of these animals has deeply damaged this planetary nutrient recycling system, threatening fisheries and ecosystems on land, a team of scientists reports.
Gaye Rosier's insight:

The planet has a natural balance between ecosystems which man has disrupted.

Seagrasses provide the foundation of highly productive ecosystems present along the coasts of all continents except Antarctica, where they rival tropical rain forests and coral reefs in ecosystem services.

Ocean acidification impacting population demography, hindering adaptation potential

Ocean acidification impacting population demography, hindering adaptation potential | Marine Conservation Research | Scoop.it
Ocean acidification may be impacting upon the population dynamics of marine species and hindering their ability to genetically adapt to future climate change. These are the findings of a team of scientists, following an investigation into how the gastropod Hexaplex trunculus has responded to ocean acidification over multiple generations.
Gaye Rosier's insight:

Those at the CO2-rich site were found to have a significantly lower mean shell length, and smaller, thinner shells than those at the two neutral sites. They also found significantly fewer females present in the Low pH site (32.26%), while the sex ratio in the control pH sites was around 50%.

Ocean heat content reveals secrets of fish migration behaviors: Study uses hurricane forecasting tool to show fishes affinity for ocean fronts and eddies

Ocean heat content reveals secrets of fish migration behaviors: Study uses hurricane forecasting tool to show fishes affinity for ocean fronts and eddies | Marine Conservation Research | Scoop.it
A new method has been developed to estimate fish movements using ocean heat content images, a dataset commonly used in hurricane intensity forecasting. With Atlantic tarpon as the messenger, this is the first study to quantitatively show that large migratory fishes, such as yellowfin and bluefin tunas, blue and white marlin, and sailfish have affinities for ocean fronts and eddies.
