Tiny crustaceans discovered preying on live jellyfish during harsh Arctic night
Scientists used DNA metabarcoding to show for the first time that jellyfish are an important food for amphipods during the Arctic polar night in waters off Svalbard, at a time of year when other food resources are scarce. Amphipods were not only observed to feast on ‘jelly-falls’ of dead jellyfish, but also to prey on live jellyfish. These results corroborate an ongoing ‘paradigm shift’ which recognizes that jellyfish aren’t a trophic dead-end but an important food for many marine organisms.
Being a better friend to wetlands
What better day to start being better friends with wetlands than World Wetlands Day? Here are some ideas to get you started:
Call for your letters to the Sea
Onewater is currently accepting “Letters to the Sea” from this age group. These will be recited at our Somos OceanoS ‘Voices from the Shore' event at the 2024 UN Ocean Decade Conference in Barcelona.
Galápagos penguin is exposed to and may accumulate microplastics at high rate within its food web, modelling suggests
And excretion rate may determine whether or not these microplastics also bioaccumulate across trophic levels
Marine species discovered in 2023
In 2023, we made many new discoveries - truly amazing life hidden deep - and not so deep - beneath the waves. Here are just a few of them.
Is there colonialism in climate targets?
The famous 1.5C threshold for global warming by 2100 has been enshrined by the Paris Agreement, but is the target truly equitable?
How deep sea knowledge can support climate policies
Young Researchers from La Laguna to join Ocean Census expedition in Tenerife, providing data and knowledge that could support climate policies.
Bacteria linked to mass death of sea sponges weakened by warming Mediterranean
In 2021, divers off the Turkish Aegean coast first observed dark stinging sponges dying in great numbers. Researchers have now sampled three species of pathogenic Vibrio bacteria, previously known to infect unrelated marine animals, from diseased and dying sponges. Evidence suggests that vibriosis may be a secondary illness that affects already weakened sponges, but is not necessarily the primary agent of the novel disease.
World-first system to monitor the ‘seafood basket’ of Australia
Australia’s national science agency, CSIRO, has completed initial testing of a ‘weather service’ for water quality in the Spencer Gulf in South Australia – which provides much of the country’s seafood – with plans to use the technology in local seafood farms.
