Researchers: There is a need for more accurate accounting of nitrous oxide from agricultural crop residues      (via sciencedaily.com)     Original source 

According to researchers, there is a need for changing the way of accounting greenhouse gases from agriculture. The current inventory of nitrous oxide from plant residues relies solely on the amount of nitrogen in the residues, while crucial factors such as the degradability of plant residues are not included. According to the researchers, this leads to misleading inventories, which also misrepresents possible mitigation measures.

New mollusk and crustacean species in symbiosis with worms in dead coral rocks      (via sciencedaily.com)     Original source 

The symbiotic communities of invertebrates in dead coral gravel on the shallow, warm-temperate coast of the Kii Peninsula in western Japan. New bivalve species and sideswimmer have been found to live communally with the greenish Bonellia spoonworm. Live-in symbionts share the burrows of other organisms in sand and mud on the seabed. However, studies on burrow niches in rigid substrates, such as rocks on the seabed, have been scarce.

Researchers study one of the world's darkest rivers      (via sciencedaily.com)     Original source 

They set out to study the Congo Basin's carbon cycle and in the process have become aware of one of the world's darkest blackwater rivers: the Ruki. In the first study on this major jungle river, an international research team explains how this blackness comes about and what it says about the river system's carbon balance.

Surprising discovery about coral's resilience could help reefs survive climate change      (via sciencedaily.com)     Original source 

A team has studied the mountainous star coral, Orbicella faveolata, to determine whether coral populations that have survived higher temperatures can pass their heat tolerance on to their offspring.  To the scientists' surprise, the results showed the opposite: The offspring from a population that is less heat-tolerant performed better when exposed to high temperatures than their counterparts from a heat-tolerant population. The findings counter the commonly held notion among scientists that if coral parents can handle the heat, so should their offspring.

Ocean circulation, ice melt and increasing tourism could all be contributing to Arctic microplastics      (via sciencedaily.com)     Original source 

Scientists measured microplastic concentrations in the highly productive Barents Sea and suggest that ocean circulation, ice melt, tourism, inadequate waste management, shipping and fishing are all likely contributors.

Climate change coping mechanism discovered in humble algae      (via sciencedaily.com)     Original source 

One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental conditions, such as ocean warming and even the reduction in the productivity of crops.

What phytoplankton physiology has to do with global climate      (via sciencedaily.com)     Original source 

Phytoplankton, tiny photosynthetic organisms in the ocean, play a crucial role in the global carbon cycle and influence Earth's climate. A new study reveals how variations in the physiology of phytoplankton, particularly regarding nutrient uptake, can impact the chemical composition of the ocean and even the atmosphere. This suggests that changes in marine phytoplankton physiology can affect global climate.

Over 40 percent of Antarctica's ice shelves reduced in volume over 25 years      (via sciencedaily.com)     Original source 

71 of the 162 ice shelves that surround Antarctica have reduced in volume over 25 years from 1997 to 2021, with a net release of 7.5 trillion tons of meltwater into the oceans, say scientists.  They found that almost all the ice shelves on the western side of Antarctica experienced ice loss. In contrast, most of the ice shelves on the eastern side stayed the same or increased in volume.  Over the 25 years, the scientists calculated almost 67 trillion tonnes of ice was exported to the ocean, which was offset by 59 trillion tons of ice being added to the ice shelves, giving a net loss of 7.5 trillion tons.

Large swings in past ocean oxygen revealed      (via sciencedaily.com)     Original source 

As the climate warms, there is major concern that Earth's ocean will lose oxygen. A study has revealed that locked in ancient deep-sea sediments is evidence for oxygen loss in the world's ocean during past glacial periods, indicating that widespread oxygen loss with current climate change may not be permanent.

Flooding that closed Alaska's Dalton Highway also caused widespread ground sinking      (via sciencedaily.com)     Original source 

The massive 2015 flooding of the Sagavanirktok River in northern Alaska had immediate impacts, including closure of the Dalton Highway for several days, but it also contributed to longer-term ground subsidence in the permafrost-rich region.

Rivers may not recover from drought for years      (via sciencedaily.com)     Original source 

Lack of rainfall is not the only measure of drought. New research shows that despite a series of storms, the impact of drought can persist in streams and rivers for up to 3.5 years.

Killer whales' diet more important than location for pollutant exposure      (via sciencedaily.com)     Original source 

Both elegant and fierce, killer whales are some of the oceans' top predators, but even they can be exposed to environmental pollution. Now, in the largest study to date on North Atlantic killer whales, researchers report the levels of legacy and emerging pollutants in 162 individuals' blubber. The animals' diet, rather than location, greatly impacted contaminant levels and potential health risks -- information that's helpful to conservation efforts.

Warm summers and wet winters yield better wine vintages      (via sciencedaily.com)     Original source 

Wine quality is notorious for varying from year to year, but what makes for a 'good year?' Researchers show that weather plays an important role in determining wine quality. By analyzing 50 years’ worth of wine critic scores from the Bordeaux wine region in relation to that year’s weather, the researchers showed that higher quality wine is made in years with warmer temperatures, higher winter rainfall, and earlier, shorter growing seasons—conditions that climate change is predicted to make more frequent.
