Vertical luminophore particle tracer profiles expressed as relative counts for replicate macrofaunal communities from the Western Barents Sea in summer 2017 and 2018

Martin Solan, Jasmin Godbold, Laura Grange, Ellie Rose Ward, Christina Wood & Adam Reed
Macrofaunal mediated redistribution of optically distinct particulate tracers (luminophores) for intact communities from the western Barents Sea after 12 days incubation. Tracer profiles are quantified from stitched composite images of all four sides of each aquarium taken using a digital SLR camera housed within a UV illuminated imaging box. Counts are expressed as relative counts (proportion of the total). Samples were collected on cruises JR16006 and JR17007. Funding was provided by 'The Changing Arctic Ocean...

Simulated yields and transmissivities for the weathered basement aquifer of Northern Ghana

Marco Bianchi, Alan MacDonald, David Macdonald & Enoch Asare
This dataset was generated with a novel process-based stochastic modelling approach to investigate the productivity and sustainability of groundwater abstractions in the Precambrian basement aquifer in Northern Ghana. The statistical distribution of the generated synthetic yield data was found in very good agreement with observed yield data from the same Ghanaian aquifer. The dataset includes more than 40,000 simulated values of maximum allowable yield and corresponding transmissivity values for different realisations of aquifer heterogeneity, net...

High resolution aeromagnetic line data in the Ross Sea Rift collected for the ANDRILL pre-site survey (2008-09 season)

Fausto Ferraccioli & Tom Jordan
A high resolution survey was flown opportunistically by BAS at the end of the AGAP aerogeophysical campaign during the 2008-09 Antarctic field season with NSF support from McMurdo. The main purpose was to collect data on the ice shelf for a radar pre-site survey for a major planned international ANDRILL drilling campaign at Coulman High. Due to lack of appropriate funding levels from several countries this ANDRILL drilling project has been postponed (https://www.icdp-online.org/projects/world/antarctica/coulman-high/) but the...

Processed line aerogravity data over the Evans Ice Stream, Southern Palmer Land region (1994/95 season)

P.C. Jones
The survey collected a total of 11,500 km of data along 22 lines, spaced 12 km apart and oriented perpendicular to the strike of both the Bouguer anomaly field, as derived from land data (McGibbon and Smith, 1991), and the major sub-ice topographical features (Doake et al., 1983). The speed of the aircraft was set to produce a sample spacing of about 60 m and the data were collected at heights between 1600 and 2000...

Processed ice shelf base picks from airborne radar depth sounding across the Pine Island Glacier Ice Shelf (2010-2011)

Hugh Corr & David Vaughan
In 2011, aerogeophysics data were acquired over Pine Island Glacier, West Antarctica on a grid comprising 30 transverse lines across the glacier, each around 20 km long, and with a spacing of roughly 500 m between the lines. The orientation of the lines was selected to be perpendicular to the surface features visible in satellite images in the central part of the ice shelf. Elevation of the ice‐surface directly beneath the aircraft was simultaneously measured...

Processed line aerogravity data over Northern Palmer Land, Antarctic Peninsula (2002/03 season)

P.C. Jones & Fausto Ferraccioli
Over 20,000 km of new aerogravity data were acquired over Palmer Land during the 2002-2003 Antarctic campaign. Profile lines were oriented E-W with N-S tie lines. Line spacing was 5 km, tie lines were 25 km apart and nominal flight altitude was 2800 m. Differential, carrier phase, kinematic GPS processing methods provided the vertical and horizontal accelerations, which dominate the raw aerogravity signal. Levelled airborne gravity data have mean accuracies of 3 mGal. We present...

NCEO LTSS: Global Ocean Lagrangian Trajectories, v1.0, 1998-2018 (OLTraj)

Giorgio Dall'Olmo & Francesco Nencioli
The National Centre for Earth Observation (NCEO) Long Term Science Single Centre (LTSS) Global Ocean Lagrangian Trajectories (OLTraj) provides 30-day forward and backward Lagrangian trajectories based on surface velocities from an ocean reanalysis. Each trajectory represents the path that a water mass would move along starting at a given pixel and a given day. OLTraj can be thus used to implement analyses of oceanic data in a Lagrangian framework. The purpose of OLTraj is to...

Jennifer Brown, Margaret J Yelland, Robin W Pascal, David S Jones, Christopher A Balfour, Geoff Hargreaves, Barry Martin, Christopher L Cardwell, Richard Pinnell, Paul S Bell, Timothy Pullen, Eunice Silva & Thomas Prime
The prototype WireWall measurement system was deployed at Hall Road Crosby (north of Liverpool UK) and measured overtopping eight times between October 2018 and March 2019. Deployments took place during tides with a range greater than the mean spring tide when there was an onshore wind. The system measured the inland distribution of wave-by-wave overtopping discharge and horizontal velocity for a couple of hours either side of high water. Wave and water level data to...

Marta Marcos Moreno, Bernat Puyol, Angel Amores, Begona Perez Gomez, Maria Angeles Fraile & Stefan A Talke
A set of historical tide gauge sea level records from Santander (Northern Spain) have been recovered from logbooks stored at the Spanish National Geographical Institute (IGN). Sea level measurements have been digitised, quality-controlled and merged into a consistent sea level time series. Vertical references among instruments benchmarks have been derived from high precision vertical levelling surveys. The observations were recorded as daily averages and are from three different instruments in two locations in Santander (Spain)....
