AndreaBozzo/ceres-open-data-index huggingface dataset:
Ice-physics transect data obtained during the SIPEX II voyage of the Aurora Australis, 2012

This dataset contains in situ measurements of ice thickness, snow thickness, and freeboard along transects on the ice-station floes from the SIPEX2012. Ice cores were collected and snow pits were measured at the 0m, 50m and 100m mark along each transect, where possible. Ice temperature measurements are taken in the field as soon as the ice core sections have been recovered from the core hole. Additionally, ice cores were taken for density analysis at a few of the ice-core sites for independent verification of ice density. In addition, electromagnetic [EM] induction measurements of total ice and snow thickness were conducted along the transect where possible.
Ice core were transferred -20oC freezer for thin-section analysis for sea-ice stratigraphy and crystallography. The cores are then cut up into suitable short sections, generally about 5cm long, to be melted  for analysis of salinity and stable oxygen isotopes. The latter will occur after the end of this cruise.
There is a data file for each ice station, containing a spreadsheet with the data. The spreadsheet contains information about how to interpret the data. 
Also included are the scanned field notes containing the hand-written (raw) data collected in the field.

ADCP data collected during the SAZ-SENSE voyage, January-February 2007

Metadata record for data from ASAC Project 2720
See the link below for public details on this project.
The overall objective is to characterise Southern Ocean marine ecosystems, their influence on carbon dioxide exchange with the atmosphere and the deep ocean, and their sensitivity to past and future global change including climate warming, ocean stratification, and ocean ... acidification from anthropogenic CO2 emissions. In particular we plan to take advantage of naturally-occurring, persistent, zonal variations in Southern Ocean primary production and biomass in the Australian Sector to investigate the effects of iron addition from natural sources, and CO2 addition from anthropogenic sources, on Southern Ocean plankton communities of differing initial structure and composition.
These samples were collected on the SAZ-SENSE scientific voyage of the Australian Antarctic Program (Voyage 3 of the Aurora Australis, 2006-2007 season). 
SAZ-SENSE VOYAGE AU0703 ADCP DATA


The complete ADCP data for cruise au0703 are in the files:
au070301.cny (ascii format)
a0703dop.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:
au0703_slow35.cny (ascii format)
a0703dop_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 averaging 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.


Important data quality information can be found in the data report referenced above.


The figure a0703difship30.eps shows the speed difference between vertical bin 2 and all other bins, where the data have been divided up into different speed classes for ship speed. The apparent vertical shear for bins ~1-10, and below bin ~40, is an error, possibly due to acoustic ringing from an air/water interface in the seachest. Data where ship speed is 0 to 1 m/s does not show this error.

Nella Dan: SIBEX II Cruise - Krill and zooplankton data

This dataset contains results from the Second International BIOMASS Experiment II (SIBEX II) cruise of the Nella Dan, January 1985. This cruise is the fourth cruise out of a series of six, investigating the distribution, abundance and population structure of krill Euphausia superba in the Prydz Bay region, Antarctica. SIBEX II was co-ordinated with South Africa, Japan and France, and 66 grid sampling stations covered an area from 58 degrees to 93 degrees East and from 60 degrees South to the Antarctic coast. At each sampling station, surveys of krill and other zooplankton were taken, as well as a CTD cast and water collection for phytoplankton pigment, nutrients and primary production measurement. Species identity and abundance data were obtained. The major species investigated were Euphausia superba, Euphausia frigidia, Euphausia crystallorophias and Thysanoessa marcuria. Other pteropods and cephalopods were also studied, as well as results from hydroacoustic surveys of krill biomass.  Summary results are listed in the documentation.

Census of Antarctic Marine Life (CAML) Archive of Project Documentation - CAML_Project_Archive.Sampling_Protocols

The Census of Antarctic Marine Life (CAML) Project Archive is a collection of scanned documents, maps, videos, and other related material that comprise the organisation and management documentation associated with a major research project of international significance. CAML measured the distribution and abundance of life in the Southern Ocean around Antarctica so that future impacts of climate change and human activities can be better understood. CAML coordinated the largest-ever survey of the Southern Ocean with 18 voyages in Antarctic waters, and inventoried over 16,000 marine species with hundreds new to science, provided DNA barcodes for 1,500 species, and has so far produced more than 600 scientific publications. CAML is a key activity of the Scientific Committee on Antarctic Research (SCAR); a subproject of the Census of Marine Life (CoML); and was a major initiative of the 2007-2009 International Polar Year (IPY).

Optimised scat collection protocols for dietary DNA metabarcoding in vertebrates

These spreadsheets provide the sequences counts for the DNA groups found in the scats of Shy Albatross at Albatross Island, Tasmania, Australia.
Samples were collected during three stages of the breeding season: Incubation (Late September 2014), Brood (December 2014) and Chick-rearing (March 2014 and 2015). Scat samples were collected from breeding birds, chicks and non-breeders.  'Breeders' were identified as individuals incubating an egg or attending a chick, whereas 'non-breeders' were usually pairs that had reoccupied the colony and were building new practice nests with no chick present. Non-breeders in the colony include immature birds that have not yet bred and mature birds of breeding age that did not breed in a particular season (e.g. no partner or insufficient body condition)
Details of the molecular methods and synthesis of this data can be found in: McInnes, J.C., Alderman, R., Deagle, B.E. Lea, M-A., Raymond, B. and Jarman, S.N. 2016. Optimised scat collection protocols for dietary DNA metabarcoding in vertebrates. Methods in Ecology and Evolution.

Collation of existing (historical) Antarctic fast ice core Chlorophyll a data

The Antarctic Fast Ice Algae Chlorophyll-a (AFIAC) dataset is a compilation of currently available sea ice chlorophyll-a data from land-fast sea ice (i.e., excluding pack ice (see ASPeCt-Bio, Meiners et al. 2012)) cores collected at circum-Antarctic locations during the period 1970 to 2015. Data come from peer-reviewed publications, field-reports, data repositories and direct contributions by field-research teams. During all campaigns the chlorophyll-a concentration (in micrograms per litre) was measured from melted ice-core sections, using standard procedures, e.g., by melting the ice at less than 5 degrees C in the dark; filtering samples onto glassfibre filters; and fluorometric analysis according to standard protocols [Holm-Hansen et al., 1965; Evans et al., 1987]. Ice samples were melted either directly or in filtered sea water, which does not yield significant differences in chlorophyll-a concentration [Dieckmann et al., 1998]. The dataset consists of 888 geo-referenced ice cores, consisting of 5718 individual ice core sections, and including 404 full vertical profiles with a minimum of three sections. Samples/sections from the remaining cores represent: i) bottom 0.05 m only (n= 32), ii) bottom 0.1 m only (n = 301), complete cores (n = 66), as well as intermittent profiles (n = 85) with at least 3 sections but gaps in-between them.
For questions about this dataset please contact: Klaus Meiners and Martin Vancoppenolle
This data compilation was carried out under the auspices of the Scientific Committee on Antarctic Research - ASPeCt program and the Scientific Committee on Ocean Research (SCOR) working group on Biogeochemical Exchange Processes at the Sea-Ice Interfaces (WG-140). It also contributes to SCOR WG-152 on Measuring Essential Climate Variables in Sea Ice (ECV-Ice).
An update to this dataset was submitted in September, 2018.

Amery Ice Shelf - hot water drill borehole AM06, RDI 300 kHz ADCP ocean velocity data 2010-2011

This dataset contains time-series of current profiles from beneath the Amery Ice Shelf obtained from an Acoustic Doppler Current Profiler (ADCP) (RDI 300 kHz broadband Workhorse) on the AM06 mooring string. The ADCP was positioned ~108 m below the base of the ice shelf and oriented to look upwards (i.e. toward the base of the shelf) to examine the water cavity boundary layer and the range (distance) from the instrument to the ice-ocean interface. Accounting for instrument displacement by ocean currents, changes in range are expected to be indicative of basal melting.
The dataset contains ~1 year of velocity data from 07/01/2010 sampled at 30 minute intervals. In the vertical, the ADCP sampled 27  bins, with a measurement every 4m.  Key variables in the dataset include ocean velocity (u, v, w), instrument orientation (pitch, roll, heading) and distance from the instrument to the ice shelf base (btdistance), as well as quality control parameters such as beam correlation (avbeamcor), strength of the return/echo amplitude (ampav) and velocity error (errv). 
Two data files are archived here, the raw data "adcp_am06_1noqc.nc" and the quality-controlled data "adcp_am06_1qc.nc". Descriptions of the quality control and post-processing are found in "readme.rtf" and notes and preliminary plots are found in "borehole2010_11.pdf".
