End of Our Icebergs

ICEBERG A43K, SOUTHERN OCEAN– Today is our last day of science. This evening we are leaving at 6pm (or 20 GMT, Greenwich Mean Time, which relates to the zero meridian that crosses Greenwich, United Kingdom. GMT time is commonly used on ships as we cross many East-West time zones and it can become confusing to keep to any one time.)

Everyone is busy trying to take that one last sample.

The last zooplankton net tow collected abundant gelatinous zooplankton, drifting animals whose bodies are almost entirely made up of water and have the consistency of gelatin.

The gelatinous zooplankton jellyfish, affectionately dubbed ‘eyeballs.’

Besides jellyfish, we have seen salps, arrow worms (chaetognaths) and comb jellies (ctenophores).
