The dataset contains raster files (.grd) for food-availability and predicted distribution of suspension feeder abundances averaged across a five year time-period before (2005-2009) and after (2011-2016) the calving of the Mertz Glacier Tongue in 2010. The following data are included: - sinking, settling and horizontal flux of food-particles along the seafloor - suspension feeder abundances and standard deviation of the predicted distribution All data has been generated as part of the paper: Jansen et al. (2018) Mapping Antarctic suspension feeder abundances and seafloor-food availability, and modelling their change after a major glacier calving. Frontiers in Ecology and Evolution

Tide gauge data collected from pressure tide gauge at Hurd Point, Macquarie Island. Data were collected between 1996-03-07 and 1996-10-27. A temporary tide gauge was installed at Hurd Point as it was suspected that there was a 6 minute wave around the island. The installation was made to determine whether this is correct. Photo Oblique aerial photos showing location of tide gauge, bench mark AUS188 and Hurd Point trig and photo mof GPS set up. Gravity meter set up adjacent tide gauge Temporary Bench Mark Survey Scans of survey field notes showing location of tide gauge in relation to Hurd Point huts, AUS188 and old Auroral Camera stand, vertical differences between AUS188, tide gauge temporary mark and tide gauge housing.

Tide gauge data collected from two platypus gauges (TG040 and TG041 - barometric) at Commonwealth Bay. Data were collected between 2007-11-27 and 2010-02-16. The gauge was a bottom mounted pressure sensor with a self-contained logger. Sea temperature and barometric pressure were also recorded. Further information is also available from the National Tidal Centre at the Bureau of Meteorology.

Tides were measured using a portable pressure transducer secured to fast ice at the mouth of Pagodroma Gorge with the transducer about 4 metres below low water line. A 30 day record was obtained. Documentation dated 2001-03-07 Beaver Lake and the Stillwell Hills In Dec 1996 - Jan 1997 a temporary pressure type tide gauge was deployed at Beaver Lake and the Stillwell Hills in open water. Timed water level measurements were made over this period. From these data a value for MSL was found for Beaver Lake and the Stillwell Hills.

Tides were measured using a portable pressure transducer secured just below low water line. A 30 day record was obtained. Numerous manual water level measurements were made to connect the tide gauge to the local benchmark. From these observations a local mean sea level was obtained. Documentation dated 2001-03-07 Beaver Lake and the Stillwell Hills In Dec 1996 - Jan 1997 a temporary pressure type tide gauge was deployed at Beaver Lake and the Stillwell Hills in open water. Timed water level measurements were made over this period. From these data a value for MSL was found for Beaver Lake and the Stillwell Hills.

Oceanographic measurements conducted on voyage 7 of the Aurora Australis of the 2002-2003 season. These data are ADCP (Acoustic Doppler Current Profiler) data. These data were collected/collated by Mark Rosenberg. Final ADCP data for voyage au0201 (SAZ mooring turnaround and iceberg B9B experiment), Aurora Australis Voyage 1 2002/2003, 17th Oct 2002 to 18th Nov 2002. * The complete ADCP data for cruise au0201 are in the file: au020101.cny (ascii format) a0201dop.mat (matlab format) * The "on station" ADCP data (specifically, the data for which the ship speed was less than or equal to 0.35 m/s) are in the files: au0201_slow35.cny (ascii format) a0201dop_slow35.mat (matlab format) * The file bindep.dat shows the water depths (in metres) that correspond to the centre of each vertical bin. * The data are 30 minute averages. Each 30 minute averageing period starts from the time indicated. (so, e.g., an ensemble with time 120000 is the average from 120000 to 123000). * ADCP currents are absolute - i.e. ship's motion has been subtracted out. * Note that the top few bins can have bad data from water dragged along by the ship. * Beware of data when the ship is underway - it's often suspect.

Possible range of qc is 0-20, with an expected range of 0-10; values of 0-4 indicate very poor data; values above 8 indicate very good data.
