🧪🦑 Check out our new study where we analysed #Mercury and #StableIsotopes in 2 #deepsea #fish species from #SouthGeorgia in the #SouthernOcean 🐟🧑‍🔬🇬🇸🇦🇶

And on a last minute call it is time to fly to #ColoradoBoulder 🇺🇸 for #PECWS (Polar Early Career World Summit) 🐧🐻‍❄️❄️

Let’s discuss the importance of #ECRs in #PolarScience and what are the challenges and directions towards the 5 #InternationalPolarYear ☃️

And we finished! ⚓

After 3 intense weeks aboard the FV SIL around #SouthGeorgia and #ShagRocks in the #ScotiaSea sampling #fish 🐟, #cephalopods 🦑🐙 and #crustaceans 🦐🦀 to access how the populations of these species we are back! ⚓

Great experience, working and learning with an amazing team! 🇦🇶

Check out our newest paper at @ecography.bsky.social on #DeepSea #FoodWebs at the #SouthernOcean 🧪🦑🇦🇶

We used #StableIsotopes to study the #benthopelagic food web at the #SouthSandwichIslands! We found a 5 #TrophicLevel web with #Toothfishes as #TopPredator 🐟🐙🦐🐧

@bas.ac.uk @ucoimbra.bsky.social
A scheme of the benthopelagic deep-sea food web of the South Sandwich Islands in the Southern Ocean. The image represents the daily vertical migration of small zooplankton (e.g. krill) and squids. Small zooplankton (trophic level 2) are eaten by squid and smaller crustaceans (e.g. shrimp) from the trophic level 3. Organisms in trophic level 3 are eaten either by larger squid and pelagic fish, or by demersal species such as crabs and fish (in trophic level 4). These are eaten by larger fish such as the toothfish (in trophic level 5). From the literature it is also in the image a potential 6th trophic level represented by a sperm whale and elephant seal that common feed in larger squid (from trophic level 4) and toothfish (from trophic level 5). It is also in the image a penguin sinking to the bottom of the ocean representing a different trophic link and a food source for deep sea organisms and frequently found in the stomachs of toothfish. The arrows have different colours representing pelagic links, demersal links, as well the transition from pelagic to demersal components and from the demersal to the pelagic component.

Destination: South Georgia 🇬🇸🐧❄️

It’s time to return to the #SouthernOcean! Short research trip (~20 days) aboard a fishing vessel to sample #fish, #cephalopods an #crustaceans to build the food web of the #SouthGeorgia shelf, an important breeding ground for #deepsea species in the archipelago! 🐟🐙🦐🦑

A different 🎄 gift this year 🎁

Check our new paper on the relevance of #Education&Outreach in the #AntarcticTreaty! We showed which delegations bring #E&O to the table, what are their targets and audiences! We also show how E&O is important to protect #Antarctica 🇦🇶🐧

Really excited to share my 1st post on bsky! And starting with our most recent paper on #SouthernOcean #Squid 🧪🦑🇦🇶

Even happier as this is the 1st paper of a student that just finished her master with us at @ucoimbra.bsky.social - Congratulations Sara (not on bsky!) 🥳

The figure shows two squid (giant warty squid Moroteuthopsis longimana) beaks (chitinous jaws of cephalopods) with the sections analysed for Hg concentrations highlighted. On the left we have a lower beak and on the right the upper beak. Beaks are a useful tool to study cephalopods as they resist to digestion and can be recovered from predators stomachs very easily. They differ between species which allows identification, grow throughout the life of individuals and allow plenty of chemical analyses to study the ecology, age, contamination, etc of these organisms.
