Peesey Swamp—a Last Interglacial (MIS 5e) marine corridor across south by T Y Pan, C V Murray-Wallace et al

Abstract Peesey Swamp on southern Yorke Peninsula, southern Australia, is a north-northwesterly south-southeasterly trending lowland depression, approximately 24 km long and 4 to 10 km wide. The richly fossiliferous mollusc and foraminiferal faunal assemblages of the last interglacial Glanville Formation in Peesey Swamp indicate that the paleoenvironment was a low- to medium-energy, sheltered sandflat to shallow-water seaway during the Last Interglacial Maximum (Marine Isotope Substage [MIS] 5e; 128–116 ka). The presence of the fossil bivalve molluscs Katelysia rhytiphora, Chlamys (Equichlamys) bifrons and Fulvia tenuicostata, in life position, indicate that the paleowater depth was ≤4 m in Peesey Swamp. The seaway cut across southern Yorke Peninsula, establishing a marine connection between southern Spencer Gulf and Investigator Strait during deposition of these taxa. Amino acid racemisation dating of the fossil marine molluscs Katelysia sp. and Fulvia tenuicostata confirms tha

WA coastal flooding risk rising rapidly, study reveals

Date Time WA coastal flooding risk rising rapidly, study reveals Scientists from The University of Western Australia have analysed WA coastal data from the last 50 years and found extreme sea levels leading to coastal flooding are rapidly increasing. The study, published in Earth’s Future, shows that a combination of sea level rise and climate cycle factors unique to WA will likely accelerate coastal flooding risks in the future.

Lead researcher Professor Ryan Lowe from the UWA Oceans Graduate School said while sea levels had been rising steadily at 3 to 5 millimetres per year in recent decades, on par with global averages, sea levels along the WA coastline were also strongly affected by El Nino and La Nina conditions.

Rare Aussie weather worries scientists

Warmer waters have been pulled south along the WA coast. Picture: BOM. Weather by Benedict Brook 1st Mar 2021 7:57 PM A rare and potentially damaging climate phenomenon has caused temperatures to soar in the waters off the Western Australia coast. It s partly down to the La Nina climate driver - but it s having a different effect in Australia s west to its east. Climate scientists have said there is a growing risk from these so-called Ningaloo Ninos in years to come as they can damage coral and marine species and drive hot air onto land. The La Nina climate driver has generally brought more moisture and cooler temperatures to Australia s east this summer.
