‘It could be the death of the museum’: why research cuts at a South Australian institution have scientists up in arms

Retrieved on: 
Freitag, April 19, 2024

“It could be the death of the museum,” says renowned mammalogist Tim Flannery, a former director of the museum.

Key Points: 
  • “It could be the death of the museum,” says renowned mammalogist Tim Flannery, a former director of the museum.
  • “To say research isn’t important to what a museum does – it’s sending shock waves across the world,” she says.

What’s the plan?

  • According to the museum’s website, this skeleton crew will focus on “converting new discoveries and research into the visitor experience”.
  • Others have tackled global questions such as the evolution of birds from dinosaurs, how eyes evolved in Cambrian fossils, and Antarctic biodiversity.

What’s so special about a museum?

  • Their remits are different, says University of Adelaide botanist Andy Lowe, who was the museum’s acting director in 2013 and 2014.
  • Unlike universities, he says, the museum was “established by government, to carry out science for the development of the state”.
  • “They’re crucial for what goes on above; you need experts not second-hand translators,” says University of Adelaide geologist Alan Collins.
  • He wonders what will happen the next time a youngster comes into the museum asking to identify a rock.
  • The museum’s Phillip Jones now uses this collection in his research, delivering more than 30 exhibitions, books and academic papers.

Continuity and community

  • Without attentive curation and the life blood of research, the collections are doomed to “wither and die”, says Flannery.
  • That raises the issue of continuity.
  • In Flannery’s words, the job of a museum curator:
    is like being a high priest in a temple.
  • Over Jones’ four decades at the museum, his relationships with Indigenous elders have also been critical to returning sacred objects to their traditional owners.
  • Besides the priestly “chain of care”, there’s something else at risk in the museum netherworld: a uniquely productive ecosystem feeding on the collections.
  • Here you’ll find PhD students mingling with retired academics; curators mingling with scientists; museum folk with university folk.
  • In the year ending 2023 for instance, joint museum and university grants amounted to A$3.7 million.

DNA and biodiversity

  • The museum has also declared it will no longer support a DNA sequencing lab it funds jointly with the University of Adelaide.
  • “No other institute in South Australia does this type of biodiversity research,” says Andrew Austin, chair of Taxonomy Australia and emeritus professor at the University of Adelaide.
  • “It’s the job of the museum.” The cuts come while the SA government plans new laws to protect biodiversity.

Why artificial submarine curtains won’t save West Antarctica’s retreating glaciers

Retrieved on: 
Mittwoch, April 3, 2024

Some researchers have recently proposed the construction of artificial structures – submarine curtains or walls – to stop the warming ocean from getting to the most rapidly melting glaciers in West Antarctica.

Key Points: 
  • Some researchers have recently proposed the construction of artificial structures – submarine curtains or walls – to stop the warming ocean from getting to the most rapidly melting glaciers in West Antarctica.
  • If effective, these interventions could save trillions of dollars in avoided coastal impacts.
  • We explore the conditions required to stop runaway glacial retreat in the Amundsen Sea Embayment, the sector of West Antarctica currently losing most ice.

Investigating the fate of West Antarctica

  • During the past 25 years, the ice sheet has already contributed 7.6mm to global sea-level rise and the rate of mass loss is accelerating.
  • Much of this increase is due to a warm ocean current that floods into deep basins close to parts of West Antarctica.
  • Satellite observations have shown extensive thinning and retreat of glaciers in this region.
  • Some scientists are concerned that this sector has already passed a threshold for irreversible retreat.
  • We have known for a long time that glaciers resting on bedrock that deepens inland could undergo runaway retreat, ultimately leading to a near total collapse of the entire West Antarctic ice sheet.

Lowering future sea-level rise

  • We explored nearly 200 different future scenarios of melting.
  • In this ensemble of experiments we explored not just different levels of cooling, but also different initial periods of melting.
  • This in turn would reduce the contribution to sea-level rise.
  • Read more:
    We can still prevent the collapse of the West Antarctic ice sheet – if we act fast to keep future warming in check

    These findings present a gloomy image for the future of West Antarctica.

  • Our results suggest that even if these bold geoengineering proposals work, there will still be ongoing ice loss and global sea-level rise for decades, even centuries, to come.

The Southern Ocean upwelling is a mecca for whales and tuna that’s worth celebrating and protecting

Retrieved on: 
Freitag, März 8, 2024

The Great Southern Australian Coastal Upwelling System is an upward current of water over vast distances along Australia’s southern coast.

Key Points: 
  • The Great Southern Australian Coastal Upwelling System is an upward current of water over vast distances along Australia’s southern coast.
  • This nutrient-rich water supports a rich ecosystem that attracts iconic species like the southern bluefin tuna (Thunnus maccoyii) and blue whale (Balaenoptera musculus brevicauda).
  • This year marks the 20th anniversary of a research publication that revealed the existence of the large seasonal upwelling system along Australia’s southern coastal shelves.

Where do the nutrients come from?

  • Only the upper 50 metres of the water column receives enough light to support the microscopic phytoplankton – single-celled organisms that depend on photosynthesis.
  • This is the process of using light energy to make a simple sugar, which phytoplankton and plants use as their food.
  • As well as light, the process requires a suite of nutrients including nitrogen and phosphorus.

What causes the upwelling?

  • These winds force near-surface water offshore, which draws up deeper, nutrient-enriched water to replace it in the sunlight zone.
  • The summer winds also produce a swift coastal current, called an upwelling jet.
  • Coastal upwelling driven by southerly winds also forms occasionally along Tasmania’s west coast.
  • Recent research suggests the overall upwelling intensity has not dramatically changed in the past 20 years.
  • The findings indicate global climate changes of the past 20 years had little or no impact on the ecosystem functioning.

What are the links between upwelling, tuna and whales?

  • They are the Australian sardine (Sardinops sagax) and the Australian krill (Nyctiphanes australis), a small, shrimp-like creature that’s common in the seas around Tasmania.
  • Sardines are the key diet of larger fish, including the southern bluefin tuna, and various marine mammals including the Australian sea lion (Neophoca cinerea).
  • Nonetheless, their timing and location appear to fit perfectly into the annual migration patterns of southern bluefin tuna and blue whales, creating a natural wonder in the southern hemisphere.
