Another belated "new paper". We used passive #eDNA sampling to evaluate the risk of biofouling species being introduced to Macquarie Island (and other Antarctic / subantarctic locations) by ships. Story from AAD: www.antarctica.gov.au/news/2026/ed... and link to paper: doi.org/10.1016/j.sc... 🧬🧪
e-DNA surveys could improve marine biosecurity – Australian Antarctic Program (News 2026)
Antarctic scientists have trialed a DNA ‘barcoding’ technique that could improve biosecurity measures that help protect polar ecosystems from invasive marine species.

While I was down South, this paper was published: MetaZooGene Intercalibration Experiment (MZG-ICE): Metabarcoding Marine Zooplankton Diversity of the Global Ocean. A nice collaboration via SCOR MetaZooGene Working Group - we evaluate #eDNA data comparability among labs. doi.org/10.1111/1755... 🧬🧪

A black browed albatross against the waves of the Southern Ocean. Photographed from RSV Nuyina near McDonald Islands #subantarctic #MarineScience
Yesterday I got to enjoy something special. RSV Nuyina passed near the McDonald Islands. I spent time on deck in the wind, spray & swell of the Southern Ocean, watching hundreds (thousands?) of seabirds hunting for food and travelling around the islands. #volcano #subantarctic #MarineScience #eDNA
Stunning views of Big Ben from the deck of RSV Nuyina at Heard Island. Big Ben is an active volcano and Australia’s highest peak. It’s usually swathed in cloud, but not yesterday! #subantarctic #MarineScience #eDNA

🧬 DNA from a biopsy sample taken from a surfacing beaked whale with a modified crossbow confirms these specimens as ginkgo-toothed beaked whales (mesoplodon ginkgodens), a species never (knowingly) seen alive. #consgen 🦊
These rare whales had never been seen alive. Then a team in Mexico sighted two
So long Hobart, see you in February! I’m on board Australia’s icebreaker RSV Nuyina, heading south for the summer to collect environmental DNA samples to study biodiversity. We left yesterday afternoon, heading to Casey Station in #Antarctica and then Heard Island ❄️ 🐧 🧬 #eDNA
