Thawimpact Project

THAWIMPACT project aims to understand how climate change impacts permafrost temperatures and dynamics in the Antarctic Peninsula region.

📢Antarctic Campaign 2024-2025
The team at Deception Island, led by Rute Cesário & Catarina Louro (IST), aimed to study Hg cycles linked to volcanic activity🌋. During the field work they collected soil/water samples from geothermal sites for microbiology & Hg/MMHg analysis🧪

📢Antarctic Campaign 2024-2025
The team at Livingston Island, led by Joana Baptista & Marcelo Fernandes (IGOT), concluded the following activities:
🔹 Maintenance of PERMANTAR observatories📉
🔹 Reinstallation of the ERT system at Reina Sofia⚡️
🔹 DGPS surveys at Hurd Peninsula🛰️

#THAWIMPACT embarked on a journey aboard El Doblon for the COASTANTAR Expedition⛵. #PERMANTAR observatories were visited, water and soil samples were collected and UAV flights were performed. Despite time constraints, we proudly report that tasks were successfully completed🎉.

[Thawimpact Project @THAWIMPACT]

The #THAWIMPACT team departed from Hurd Peninsula aboard the sailing vessel El Doblon for the #COASTANTAR expedition, concluding two intense weeks in Juan Carlos I @utm_csic. They are now set to sail ⛵️ south to explore the ice-free areas of the Antarctic Peninsula.

[Thawimpact Project @THAWIMPACT]

Joana Baptista and Henrique Zilhão are in JCI(@utm_csic) until the arrival of the sailing vessel for the @COASTANTAR expedition. Throughout the past week, they visited the rock glacier to conduct surveys using DGPS. They also collected water/soil samples.

Before arriving at the Juan Carlos I, Henrique Zilhão and Rodrigo Dias spent one week at the St. Kliment Ohridski Station 🇧🇬. During their stay, they collected soil and water samples🧪to trace specific elements and microorganisms. They also supported the #PERMANTAR network.

The #THAWIMPACT team was reunited at Hurd Peninsula🏔️. In the initial days, harsh meteorological conditions led to delays in the planned activities🌨️💨. However, the team managed to visit Reina Sofia to conduct the maintenance of the installed ERT system.
