Microplastic abundance in beach sediments of the Kiel Fjord

Kevin Schröder, Elke Kossel & Mark Lenz
We assessed the abundance of microplastic (0.2 - 5 mm) in drift line sediments from three sites in Kiel Fjord, Western Baltic. The first site is intensively used by beach visitors, the second is in close proximity to a sewage plant and the third is polluted with large-sized plastic litter. Samples were split into three grain size classes (0.2 – 0.5, 0.5 – 1.0, 1.0 – 5.0 mm), washed with a calciumchloride solution and filtered...

Emission Factors of Eastern Australian coal power plants, 2010 - 2019

Maheshinderjeet Garg
This dataset provides the emission factor (EF) values with three columns ("ave", "EF1", "EF2"). The parameter with the comment "ave" is the central estimate, and "EF1" and "EF2" are lower and upper range which represents a 95% confidence interval. The uncertainty around the central estimates of the emissions is calculated using a Monte Carlo simulation approach.

Snow thickness measurements at ice station PS118_20190301_5 during POLARSTERN cruise PS118

Stefanie Arndt & Christian Haas
Snow depth measurements were obtained using a MagnaProbe (Snow-Hydro, Fairbanks, Alaska, USA) during walking surveys on most ice stations during PS118. The walks were randomly done on the entire floe. The MagnaProbe measurements were accompanied by measurements of the total sea-ice thickness with a ground-based multifrequency electromagnetic induction instrument (GEM-2) along the same transect.

Sulfur hexafluoride (SF6) traces of Moulin L41A on the Greenland Ice Sheet measured in summer 2012

David M Chandler, Jemma Wadham, Peter Nienow, Samuel H Doyle, Andrew Tedstone, Jon Telling, Jonathan Hawkings, Jonathan Alcock, Benjamin Linhoff & Alun L Hubbard
SF6 gas traces were injected into Moulin L41A, and samples were collected in the proglacial river near Leverett Glacier terminus (67.09N, -50.23E). A total of 11 traces were carried out between 16 June and 6 August, 2012. Tracers were injected at ~19:00 hrs, shortly after the peak daily moulin discharge (typically between 15:00 and 19:00 hrs). Tracer concentrations were monitored by collecting water samples from the proglacial river draining Leverett Glacier and were analysed by...

Proglacial river discharge from the Greenland Ice Sheet measured in spring/summer 2012

David M Chandler, Jemma Wadham, Peter Nienow, Samuel H Doyle, Andrew Tedstone, Jon Telling, Jonathan Hawkings, Jonathan Alcock, Benjamin Linhoff & Alun L Hubbard
Proglacial river discharge was monitored using stage measurements (collected by a HOBO pressure sensor) and dye dilution gauging at a stable bedrock section near the terminus of Leverett Glacier, 67.09N -50.23E. Here we report hourly means of measurements made at 1 minute intervals. The same method has been used at this site over several melt seasons and is described in detail by Bartholomew et al. (2011, http://dx.doi.org/10.1029/2011GL047063) and Tedstone et al. (2013, http://dx.doi.org/10.1073/pnas.1315843110).

Early meteorological records from Extremadura region, SW Iberia (CliPastExtrem)

Meteorological observations made in the region of Extremadura (SW Iberia) from 1826 to mid-20th century have been retrieved. Variables such as air temperature, atmospheric pressure, precipitation, wind direction and humidity, among other, were recorded in these observations. In total, more than 700000 instrumental data were digitized (79.8 % with daily resolution).

Pore Water Nutrient Data from Surface Sediments from Sonne Expedition SO245 \"UltraPac\", supplement to: Ferdelman, Timothy G (2016): RV SONNE SO245 Cruise Report / Fahrtbericht, Antofagasta, Chile: 17.

Max-Planck-Institut für marine Mikrobiologie, Bremen, 104 pp

Timothy G Ferdelman, Gabriele Klockgether & Claudia Ehlert
Sediment pore water nutrient chemistry on surface sediments from the South Pacific Gyre. Pore waters were obtained by Rhizone sampling of sub-cores from box-cores retrieved during Expedition SO245. Nutrient were determined after three-fold dilution onboard on a QuAAtro39 autoanalyser (Seal Analytical) using the method based on Strickland and Parsons, 1972.

Geometries of fresh lava margins and some relevant synthetic fractals

Ethan I Schaefer
These shapefiles record the geometries of 15 intervals along geomorphically fresh lava margins as well as 4 relevant synthetic (pseudo)fractal geometries. Each eponymous shapefile records those intervals from one region (in an appropriate coordinate system): Hawaii, Iceland, Idaho, and synthetic. The margin geometries were collected in the field using differential GNSS techniques with a nominal precision of <3 cm. While walking each margin, the rover mast was manually kept vertical. Accidental tilt of the mast...
