Scientific women get together in plan for marine protected area for Antarctica Peninsula
All-female scientific coalition calls for marine protected area for Antarctica Peninsula Plus other ways to help penguins, whales, and seabirds, EurekAlert, UNIVERSITY OF SYDNEY, Research News 19 Oct 20, The Western Antarctic Peninsula is one of the fastest warming places on earth. It is also home to threatened humpback and minke whales, chinstrap, Adélie and gentoo penguin colonies, leopard seals, killer whales, seabirds like skuas and giant petrels, and krill – the bedrock of the Antarctic food chain.With sea ice covering ever-smaller areas and melting more rapidly due to climate change, many species’ habitats have decreased. The ecosystem’s delicate balance is consequently tilted, leaving species in danger of extinction.
Cumulative threats from a range of human activities including commercial fishing, research activities and tourism combined with climate change is exacerbating this imbalance, and a tipping point is fast approaching.
Dr Carolyn Hogg, from the University of Sydney School of Life and Environmental Sciences, was part of the largest ever all-female expedition to the Antarctic Peninsula, with the women in STEMM initiative, Homeward Bound, in late 2019. There, she witnessed the beauty and fragility of the area, and the negative impacts of climate change and human activity on native species, first-hand. As part of the Homeward Bound program she learnt about the science, conservation and governance of Antarctica.
In a new commentary piece published in Nature, Dr Hogg and her colleagues from the expedition outline these threats, and importantly, offer ways to counter them. More than 280 women in STEMM who have participated in the Homeward Bound initiative are co-signatories to the piece.
A global initiative, Homeward Bound ‘aims to elevate the voices of women in science, technology, engineering mathematics and medicine in leading for positive outcomes for our planet’.
Women are noticeably absent in Antarctica’s human history, which is steeped in tales of male heroism. Female scientists are still a minority in the region’s research stations.
“Now, more than ever, a broad range of perspectives is essential in global decision-making, if we are to mitigate the many threats our planet faces,” said Dr Hogg.
“Solutions include the ratification of a Marine Protected Area around the Peninsula, set to be discussed on 19 October, at a meeting of a group of governments that collectively manage the Southern Ocean’s resources,” said Dr Hogg. “The region is impacted by a number of threats, each potentially problematic in their own right, but cumulated together they will be catastrophic.”
Decreasing krill affects whole ecosystem
The Peninsula’s waters are home to 70 percent of Antarctic krill. In addition to climate change, these krill populations are threatened by commercial fishing. Last year marked the third largest krill catch on record. Nearly 400,000 tonnes of this animal were harvested, to be used for omega-3 dietary supplements and fishmeal.
“Even relatively small krill catches can be harmful if they occur in a particular region, at a sensitive time for the species that live there,” said Dr Cassandra Brooks, a co-author on the comment from the University of Colorado, Boulder. “For example, fishing when penguins are breeding lowers their food intake, and affects their subsequent breeding success. A Marine Protected Area will conserve and protect this unique ecosystem and its wildlife, and we need to implement it now.”
Climate change is fundamentally altering the Western Antarctic Peninsula:……
Three ways to protect the Peninsula
1. A Marine Protected Area (MPA) designation for the waters………
2. Protect land areas ………
3. Integrate conservation efforts…….
