Bending Ice

The Darwin Glacier feeds into the much larger Ross Ice Shelf. Over the transition between grounded and floating ice the influence of the tides increases. Today we distributed seven highly-sensitive tiltmeters across the grounding zone to measure the flexure due … Continue reading

Neap Tide

Interaction of the sun, the moon and our planet cause tides. In the Ross Sea the tidal cycle roughly repeats itself every 14 days. This oscillation can be approximated using ocean tide models. Yesterday we installed a GPS station on … Continue reading

Icesolated

We spent the last two days in our little yellow tents. Katabatic winds of 35 knots, gusting to 45 knots, caused snow to drift around our camp. The wind eroded the “Great Wall of Antarctica” already !       … Continue reading

The TIDEx-team

An increasing number of glaciers in Antarctica are accelerating, thinning and experiencing rapid ice loss, while others are remaining stable. Likewise, some ice shelves (the floating extension of the glacier) are thinning, driven by an increase in ocean temperature, and … Continue reading
