Global long-term data simply doesn’t exist for jellyfish, so scientists struggle to predict, track and mitigate their potential effects.

Born on July 30, 1920, geologist and cartographer Tharp changed scientific thinking about what lay at the bottom of the ocean – not a featureless flat, but rugged and varied terrain.
Recent shark-related deaths fuel the debate around the best way to keep people safe in the water, without hurting marine wildlife.
Traditional ecological knowledge involves an interaction between cultural practice, cultural belief and adaptive capacity to deal with climate impacts.

Microscopic ocean phytoplankton feed a “biological pump” that carries carbon from the surface to deep waters. Scientists have found that this process stores much more carbon than previously thought.
Using new technology to answer questions about shark reproduction.

Researchers are using a newly developed satellite tag to study previously unknown aspects of tiger shark reproduction. This approach could be used on other difficult-to-study shark species.
Empatheatre’s latest production is more than a play about three characters who live near the sea. It’s a model for collective consultation on how to save the ocean.

Icelandic whalers have killed more than 1,700 whales since a global ban was adopted in 1986 – up to 2019, when no hunts took place. Is Iceland quietly getting out of the business?
The ocean pool is a familiar sight in New South Wales but isn’t nearly as common elsewhere.

New South Wales boasts many wonderful ocean pools, thanks to a combination of climate, geology, culture and prosperity. Despite concerns about costs, economic and health benefits far outweigh these.
Projects based on comprehensive understanding of gender norms in coastal communities will contribute to improved community wellbeing.

How did whales that feed on tiny prey evolve into the largest creatures on Earth? And why don’t they get even bigger?
Indonesia will face new challenges as current released IPCC reported states that oceans and cryosphere are melting in accelerated rate.

Shark fisheries in Indonesia are an important economic resource in several areas. Hence, stronger regulations are needed to prevent declines in shark population.

Although less well known than its cousins, coral reefs and mangroves, seagrass plays a crucial role in climate change mitigation.
