from the editor

For centuries, our waters have been seen as a limitless bounty of food. Day and night, fishers go out to sea hoping for a good catch, but as divers, we value the ocean as something much more than a means of sustenance: Our sanctuary is often found beneath the surface, where marine life thrives. But in the last century, the demand for seafood has skyrocketed, and fishers have resorted to unsustainable practices. Today, over 60 percent of the world’s fish stocks are fully fished, and 40 percent of recorded marine species have decreased in the last 40 years. In response, conservationists, scientists, and governments have been in continuous dialogue with local communities to protect the world’s most precious underwater ecosystems. While protected areas have been popping up more rapidly in recent…

scientists inadvertently mutate plastic-eating enzyme

An inadvertently-engineered creation discovered by US Department of Energy’s National Renewable Energy Laboratory (NREL) and the UK’s University of Portsmouth may offer a vital solution to the problem of plastic pollution. The PET-digesting enzyme Ideonella sakaiensis, also known as PETase, was first discovered in 2016 by Yoshida et al., who found the bacterium living in the soil at a recycling plant in Japan that was piled with used bottles. This bacterium was unique as it could use polyethylene terephthalate (PET) as its major carbon and energy source. In other words, these bacteria can simply feed on plastic used to make disposable beverage bottles for survival and growth. With this discovery, NREL and the University of Portsmouth dedicated a research team to determine the enzyme’s structure. While conducting the research, the team inadvertently…

words of wisdom

“When it comes to our seas and oceans, the challenge is global so the answer must be too” MICHAEL GOVE (UK Environment Secretary) “In the maritime world, sustainability means that the more you regulate, the more productive your ocean will be” SUSI PUDJIASTUTI (Minister of Fisheries and Marine Affairs for the Republic of Indonesia) “We can all play a significant part in dealing with the plastic problem. But the scientific community who ultimately created these “wonder-materials,” must now use all the technology at their disposal to develop real solutions” JOHN MCGEEHAN (Professor of Structural Biology, University of Portsmouth)…

uk bans the sale of plastic straws and cotton buds

The British Government has announced an end to the sale of plastic straws, drink stirrers and plastic-stemmed cotton buds at the start of the Commonwealth Heads of Government Summit. Subject to the consultation, which the Environment Secretary Michael Gove will launch later this year, UK authorities are prepared to ban the sale of these items in Britain under plans to protect their rivers and seas and meet their 25 Year Environment Plan ambition to eliminate avoidable plastic waste. The announcement comes as the Prime Minister Theresa May urged all Commonwealth countries to sign up to the newly-formed Commonwealth Clean Oceans Alliance and take action, be this through a ban on microbeads, a commitment to cutting down on single-use plastic bags, or other steps to eliminate plastic pollution. Single-use plastic items such as straws,…

new study shows genetic diversity of coral could extend our chance to save the great barrier reef

A study published in PLOS Genetics recently discovered that there may be an extra 50 years for us to save the corals of Australia’s Great Barrier Reef. Researchers from the University of Texas at Austin, the University of Melbourne, and the Australian Institute of Marine Science have found that corals in the Great Barrier Reef have enough genetic diversity to survive rising ocean temperatures for another century, double the previous estimate. The scientists obtained their results through a mix of genetic sampling and computer simulations, focusing on the staghorn coral Acropora millepora, a significant species in building the Great Barrier Reef. Corals within this species have been found to be more heat resistant than others. When the coral colonies reproduce, they release millions of larvae that float on ocean currents before…

new manta ray cleaning station and two goby species discovered

On April 12, 2018, an Indonesian luxury private charter vessel partnered with Conservation International (CI) for a high-tech scientific voyage across Raja Ampat to raise awareness for the protection of manta rays. Ichthyologist, Dr. Gerry Allen, and Vice President of CI’s Asia Pacific Marine Programme, Dr. Mark Erdmann, were at the helm of the mission, with the aim of conducting research on the manta population and their migration patterns, while also surveying coral reef fish biodiversity. The trip made scientific headway with the discovery of a new manta ray cleaning station in Dayang and confirmation of another suspected cleaning station in Ayau , identifying at least 25 new manta individuals and two species of goby – the Grallenia goby and the Silhouettea goby, the names of which are yet to be decided. “Until…
