Functional outline of the data portal search interface. The Data Access Portal has information in 3 columns. An outline of the content in these columns is provided above. When first entering the search interface, all potential datasets are listed. Datasets are indicated in the map and results tabulation elements which are located in the middle column. The order of results can be modified using the "Sort by" option in the left column. On top of this column is normally relevant guidance information to user presented as collapsible elements.
If the user want to refine the search, this can be done by constraining the bounding box search. This is done in the map - the listing of datasets is automatically updated. Date constraints can be added in the left column. For these to take effect, the user has to push the button marked search. In the left column it is also possible to specific text elements to search for in the datasets. Again pushing the button marked "Search" is necessary for these to take action. Complex search patterns can be constructed by changing the operators used in the text field and prefixing words with '+' and '-' to indicate whether they have to be present or should not be present in the results.
Other elements indicated in the left and right columns are facet searches, i.e. these are keywords that are found in the datasets and all datasets that contain these specific keywords in the appropriate metadata elements are listed together. Further refinement can be done using full text, date or bounding box constraints. Individuals, organisations and data centres involved in generating or curating the datasets are listed in the facets in the right column.

Abstract:
Three separate airborne radar surveys were flown during the austral summer of 2016/17 over the Filchner Ice Shelf and Halley Ice Shelf (West Antarctica), and over the outlet glacier flows of the English Coast (western Palmer Land, Antarctic Peninsula) during the Filchner Ice Shelf System (FISS) project. This project was a NERC-funded (grant reference number: NE/L013770/1) collaborative initiative between the British Antarctic Survey, the National Oceanography Centre, the Met Office Hadley Centre, University College London, the University of Exeter, Oxford University, and the Alfred Wenger Institute to investigate how the Filchner Ice Shelf might respond to a warmer world, and what the impact of sea-level rise could be by the middle of this century.
The 2016/17 aerogeophysics surveys acquired a total of ~26,000 line km of aerogeophysical data. The FISS survey consisted of 17 survey flights totalling ~16,000 km of radar data over the Support Force, Recovery, Slessor, and Bailey ice streams of the Filchner Ice Shelf. The Halley Ice Shelf survey consisted of ~4,600 km spread over 5 flights and covering the area around the BAS Halley 6 station and the Brunt Ice Shelf. The English Coast survey consisted of ~5,000 km spread over 7 flights departing from the Sky Blu basecamp and linking several outlet glacier flows and the grounding line of the western Palmer Land, including the ENVISAT, CRYOSAT, GRACE, Landsat, Sentinel, ERS, Hall, Nikitin and Lidke ice streams.
Our Twin Otter aircraft was equipped with dual-frequency carrier-phase GPS for navigation, radar altimeter for surface mapping, wing-tip magnetometers, an iMAR strapdown gravity system, and a new ice-sounding radar system (PASIN-2).
We present here the full radar dataset consisting of the deep-sounding chirp and shallow-sounding pulse-acquired data in their processed form, as well as the navigational information of each trace, the surface and bed elevation picks, ice thickness, and calculated absolute surface and bed elevations. This dataset comes primarily in the form of NetCDF and georeferenced SEGY files. To interactively engage with this newly-published dataset, we also created segmented quicklook PDF files of the radar data.Access: otherRestrictions-

Abstract:
These data files contain the records of isotopes, anions, cations and organic compounds measured in the Bouvet Island ice core. The Bouvet ice core was collected as part of the Antarctic Circumnavigation Expedition (ACE) 2016-2017, and is the first ever ice core collected on the island. All analyses was carried out at the British Antarctic Survey, Cambridge, United Kingdom between 2016 and 2018. Analyses were carried out by analytical staff and a PhD student. Isotopes were measured using a Picarro instrument, anions and cations on a Dionex Intergrion Ion Chromatograph, and organics using High-Performance Liquid Chromotography Mass Spectrometry (HPLC-MS). Isotopes, anions and cations are measured as discreet 5cm core samples, while organics are measured at annual resolution core samples.
This data forms part of a suite of ice cores from the sub-Antarctic islands collected on the ACE cruise 2016-2017, for which anion, cation and isotope data will be made available separately.

Work by Amy King was jointly supported by Selwyn College, Cambridge, and the NERC Doctoral Training Programme [grant number NE/L002507/1]. ACE and Elizabeth Thomas received funding from Ecole Polytechnique Federale de Lausanne, the Swiss Polar Institute, and Ferring Pharmaceuticals Inc.

Abstract:
This data set contains annual surface melt onset and freeze onset dates across all glaciers in the Hindu Kush Himalayas (HKH) retrieved from time series synthetic aperture radar (SAR) imagery. The data set was based on analysis of C-band Sentinel-1 A/B SAR time series, comprising 32,741 Sentinel-1 A/B SAR images. The duration of annual glacier surface melt was determined for 105,432 mapped glaciers (83,102 km2 glacierized area) during the calendar years 2017-2020.Access: These data are freely, openly, and fully accessible, provided that you are logged into your NASA Earthdata profile (https://urs.earthdata.nasa.gov/). -

Abstract:
This data set contains strapdown aerogravity data collected during an airborne radar survey of the Brunt Ice Shelf as part of the NERC/BAS Life Time of Halley project. Unlike traditional stabilised platform gravity surveys strapdown gravity techniques, using an Inertial Measurement Unit (IMU) rigidly attached to the aircraft as the sensor, allow collection of gravity data during draped or turbulent flight. This was a key factor allowing for data collection during a dedicated radar survey. The survey was flown draped with an average height above the ice surface of 420m, and includes 4716 km of new data. The aircraft used was the BAS aerogeophysicaly equipped twin otter VP-FBL. Data are available in both Geosoft database (.gdb) and ASCII file formats (.xyz).Access: otherRestrictions -
