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.

And excretion rate may determine whether or not these microplastics also bioaccumulate across trophic levels

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.

The famous 1.5C threshold for global warming by 2100 has been enshrined by the Paris Agreement, but is the target truly equitable?

Young Researchers from La Laguna to join Ocean Census expedition in Tenerife, providing data and knowledge that could support climate policies.

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.

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. 

Plastic waste in the water might be stopping - or interrupting - some shrimp-like creatures from reproducing. In a unique study, the ability of ‘shrimp like’ creatures to reproduce successfully was found to be compromised by chemicals found in everyday plastics.

Researchers from Australia studied the influence of pollution on the sex ratio of clutches of sea green turtles. This species is at risk of extinction from a current lack of male hatchlings. They concluded that exposure to the heavy metals cadmium and antimony, accumulated by the mother and transferred to her eggs, may cause embryos to be feminised. Pollution may thus compound the female-biasing influence of rising global temperatures on green sea turtles.
