A thorough understanding of movement patterns of a species is critical for designing effective conservation and management initiatives. However, generating such information for large marine vertebrates is challenging, as they typically move over long distances, live in concealing environments, are logistically difficult to capture and, as upper-trophic predators, are naturally low in abundance. Large-bodied, broadly distributed tropical shark typically restricted to coastal and shelf habitats, the great hammerhead shark Sphyrna mokarran epitomizes such challenges.

Scientists have warned that oxygen content in the world's oceans has decreased by more than two per cent since 1960, putting marine life at high risk of devastating consequences.

The bunker oil spilt by Indian flagship vessel M T Dawn Kancheepuram after it collided with the Isle of Man's vessel B W Maple could persist in the environment for months or years if not removed.

The Environment Ministry may issue a show cause notice to the Kamarajar Port (Ennore port) in Chennai for "mishandling" the oil spill following a collision between two ships last month.

Despite the rapid increase in the use of unmanned aerial vehicles (UAVs) in marine mammal research, knowledge of the effects of UAVs on study animals is very limited. We recorded the in-air and in-water noise from two commonly used multi-rotor UAVs, the SwellPro Splashdrone and the DJI Inspire 1 Pro, to assess the potential for negative noise effects of UAV use. The Splashdrone and Inspire UAVs produced broad-band in-air source levels of 80 dB re 20 μPa and 81 dB re 20 μPa (rms), with fundamental frequencies centered at 60 Hz and 150 Hz.

If countries abide by the Paris Agreement's global warming target of 1.5 degrees Celsius, potential fish catches could increase by six million metric tonnes per year, estimates a new study.

At hydrothermal vents in Longqi or ‘Dragon’s Breath’, 1,243 miles southeast of Madagascar, scientists have discovered unique marine life, including six species new to science.

A new study has found that higher water temperatures have ravaged the Great Barrier Reef, causing the worst coral bleaching recorded by scientists.

Plastic pollution threatens to wipe 7.4 per cent off the value of Sydney homes in areas where litter is apparent, a new report shows.

The government is failing to protect the reef from the effects of shipping disasters, according to environmental lawyers, who say inaction to secure remediation funds will become a bigger problem a
