Why seagrass is so important to our environment.

There's no 'garbage patch' in the Southern Indian Ocean, so where does all the rubbish go?

The next 24 hours will be the most challenging so far for Vendée Globe race leader Charlie DALIN (Apivia), especially through this evening and tonight as he will pass as close as he dare to the centre of a Southern Ocean low pressure system which is forecast to bring him gusts over 55kts and big seas. He told his team yesterday 'this is the biggest, most powerful storm I have had through since the start'. So today will mostly be about pushing on and preparing himself and his Apivia.

The study of ocean bottom pressure (OBP) helps to understand the changes in the sea level budget and ocean deep circulation. In this study, the characteristics and mechanisms of interannual OBP variability in the Southern Indian Ocean are examined using Gravity Recovery and Climate Experiment (GRACE) satellite data from 2003 to 2016. Results show that there are two energetic OBP centers in the Southern Indian Ocean (50°-60°S, 40°-60°E and 45°-60°S, 80°-120°E). The OBP magnitudes at two centers have strong variability on interannual time scales, and their values are larger during austral summer (NDJF) and winter (JJAS). Atmospheric forcing plays an important role in local OBP variability. The high (low) sea level pressure (SLP) over the Southern Indian Ocean benefits positive (negative) OBP anomalies via the convergence (divergence) of Ekman transport driven by local wind. Such SLP anomalies are related to the Southern Annular Mode (SAM), Southern Oscillation (SO) and Indian Ocean dipole (IOD). SAM can influence the OBP changes in both austral summer and winter, while SO and IOD have positive correlations with OBP variability during austral summer and austral winter, respectively. These results are validated by a mass-conservation ocean model, which further confirms the importance of atmospheric forcing on the interannual OBP variations.

Not so long ago, hijackings by Somali pirates were a daily part of the headlines. But this year no attacks were reported in east African waters, according to data from the United Nation's International Maritime Organization.

News across the world has been dominated by the tragic mystery surrounding the disappearance of Malaysia Airlines flight MH370 somewhere in the southern Indian Ocean. Many people have been asking CSIRO for our take on the situation, the ocean, the technology being used to find the debris of the plane - so we wanted to let you know how our technology is being used and how we're assisting the Australian Maritime Safety Authority (AMSA).

Octopuses are generally loners. Squids often form schools. But cuttlefish (or seacuttles if you will)…they outright just don't get along with one another. In the video below two Giant Australian Cuttlefish males that are bit cranky fight over a female. They are both flashing the characteristic Zebra "Don't F**K With Me" pattern. Make sure you watch after 2 minutes when they really throw down.

Scientists are embarking on a two-year programme to identify what underlying mechanisms keep seas so healthy in the Chagos Archipelago.

Ocean lovers are often left out of the bigger environmental discussions and so struggle to see how they can do their part to stop climate change.

The Gulf of Carpentaria off Australia's northern coast has one of the highest rates of abandoned fishing nets, or so-called ghostnets, anywhere in the world. In fact, up to three tonnes of netting washes ashore each year for every kilometre of coastline.

Mangrove forests are dynamic ecosystems found along low-lying coastal plains along tropical, subtropical, and some warm-temperate coasts, predominantly on tidal flats fringing deltas, estuaries, bays, and oceanic atolls. These landforms present varied hydrodynamic and geomorphological settings for mangroves to persist and could influence the extent of within-site propagule transport and subsequent local regeneration. In this study, we examined how different landform characteristics may influence local genetic diversity, kinship, and neighborhood structure of mangrove populations. To do so, we considered independent populations of Avicennia marina, one of the most abundant and widespread mangrove species, located in estuarine and coastal bay environments spread across the Western Indian Ocean region. A transect approach was considered to estimate kinship-based fine-scale spatial genetic structure using 15 polymorphic microsatellite markers in 475 adult A. marina trees from 14 populations. Elevated kinship values and significant fine-scale structure up to 30, 60, or 90 m distances were detected in sheltered systems void of river discharge, suggesting a setting suitable for very local propagule retention and establishment within a neighborhood. Slopes of a linear regression over restricted distance within 150 m were significantly declining in each sheltered transect. Contrastingly, such a spatial structure has not been detected for A. marina transects bordering rivers in the estuarine systems considered, or alongside partially sheltered creeks, suggesting that recruitment here is governed by unrelated carried-away mixed-origin propagules. South African populations showed strong inbreeding levels. In general, we have shown that A. marina populations can locally experience different modes of propagule movement, explained from their position in different coastal landforms. Thus, the resilience of mangroves through natural regeneration is achieved by different responses in
