Geochemical and petrological data pertaining to the eruptive deposits of 1883 caldera-forming eruption of Krakatau (NERC grants NE/L002612/1, NE/N014286/1, NE/T002026/1)

Geochemical data has been collected on samples from new exposures of the 1883 deposits, revealed by the 2018 tsunamigenic flank collapse of Anak Krakatau, which provides improved stratigraphic context. Whole-rock data taken by X-ray Florescence shows no systematic stratigraphic correlation. Chemical data for transects across, and spot points on, plagioclase phenocrysts, including some trace element data, all obtained using Electron Probe Microanalysis (EPMA), with Backscatter electron (BSE) images of crystals, obtained using Scanning Electron Microscope, reveal complex zoning profiles. However, chemical data for transects across pyroxene phenocrysts, obtained using EPMA, show this phenocryst phase is largely unzoned. The dataset also includes chemical data for spots on Fe/Ti oxides, included on the rims of pyroxene, and obtained using EPMA. Matrix glass chemistry, obtained via EPMA, shows that the early eruptive ash is more evolved than the pyroclastic material that follows, and that there is a slight overall trend to a more homogenous, less evolved melt composition. The 1883 eruption of Krakatau was a large, cardera-forming eruption that caused approximately 36,000 fatalities. It is also the only eruption of its size to have accompanying written accounts.

Meteorological Data from BGS Virkisjökull-Falljökull Glacier Observatory, 2009-2020

This dataset presents meteorological records from 3 weather stations around a glacier in southeast Iceland from 2009-2020. The weather stations were installed as part of British Geological Survey’s Glacier Observatory project, and were positioned at different altitudes close to the ice to record glacier weather. The data is in text format, and records key meteorological parameters including temperature, relative humidity, atmospheric pressure, precipitation, wind speed and direction, and solar irradiance. The weather stations were placed around Virkisjökull-Falljökull, an outlet glacier of the Öraefajökull ice cap in south east Iceland (AWS1 at 16°48'19"W, 63°57'53"N; AWS3 at 16°47'5"W, 63°58'13"N, and AWS4 at 16°48'7"W , 63°59'52"N). AWS1 was installed in September 2009, with AWS3 installed in September 2010, and AWS4 in September 2011. AWS3 and AWS4 were decommissioned in August 2018, and AWS1 in May 2020. AWS1 was located 100m from the current glacier margin at 156m a.s.l.; AWS3 sat 50m from the icefall at 444m a.s.l.; and AWS4 was situated on a clifftop overlooking the glacier at 858m a.s.l., close to the Equilibrium Line Altitude of the glacier. These were positioned at different altitudes to determine changes in weather parameters with height, thus producing for example, temperature or humidity gradients. The three stations were wirelessly linked, allowing data from the upper stations to be offloaded to the datalogger on the lower station. On-site downloads were completed using Campbell Scientific LoggerNet 4.x series software. AWS1 maintained mobile phone telemetry enabling automatic remote downloads of data from all stations on a daily basis, and remote access for software updates and health checks. Each AWS supported a slightly different sensor array, depending on the requirements of the site, and were mounted on 1.5m Campbell Scientific tripods. All of the stations were designed around a Campbell Scientific CR800 datalogger, and were solar powered, using combinations of PV panels up to 100W, supplying a Campbell Scientific 25Ah battery mounted on the tripod, plus a 110Ah gel cell battery back up in a separate housing. The data will be of use to researchers and students interested in the weather of southeast Iceland, glacier climate, local influence of glaciers on more regional synoptic weather systems, glacier climate modellers, glacier hydrologists and hydrogeologists. The BGS project was led and coordinated by Dr Jez Everest, technical support and implementation by Heiko Buxel and data Quality Assurance and checking by Dr Jon Mackay. Any periods where equipment malfunction, testing or replacement meant that no or unreliable data were collected are indicated by a ‘NAN’ value in the datasets.

Sample Locations for Thermochronometric Analysis of Recent deformation across the Basin and Range (NERC Grant NE/N015479/1)

Locations of samples collected to constrain the recent activity on normal faults across Nevada. The geological samples will be used to measure the amount of exhumation that different normal faults of the Basin and Range experienced over the last 5 million years. The samples have been collected from granitic rocks that are expected to yield apatite crystals. (Uranium-Thorium)/Helium thermochronometry will be conducted on these samples to determine the cooling history of rocks from temperatures of approximately 70 degrees celsius. The samples are collected across Nevada at locations close to the fault to determine the most recent stages of exhumation. The ranges sampled are the Wassuk Range, White Range, Toiyabe Range, South Egan Range, Schell Range, Wheeler Range, House Range, Wasatch, Deep Greek, Ruby Range, Cortez Range, Humbolt Range, Dixie Valley, and Carson Range. Samples weigh approximately 2kg each. This sample coverage will constrain extension rates across the Basin and Range which is of interest to geologists, geodynamicists, and researchers interested in fault hazard.

Ground Penetrating Radar Data from BGS Iceland Glacier Observatory Project, 2012-2014

These files contain ground penetrating radar (GPR) data collected from the glacier margins and forelands of Falljökull and of Kvíárjökull, south-east Iceland, between 2012 and 2014. The data were collected using a Sensors and Software PulseEKKO Pro GPR system. For each glacier the data are stored in folders that indicate the month and year in which the surveys were conducted. Each GPR profile has a Sensors and Software GPR (.DT1) file, and associated header (.HD) and GPS (.GPS) files. The .HD files (which can be opened as text files) give the parameters and equipment used for each profile. GPS files are not available for some of the profiles collected on Falljökull in April 2013 (due to damage that occurred to the GPS linked with the PulseEKKO Pro system). For these profiles start, finish, and mid profile positions were recorded using differential GPS, and locations of these profiles are instead given by GIS shapefiles in the relevant folders. These datasets have been used in the publications listed below. Further information relating to the data collection methodology can be found therein.

British Geological Survey (BGS) Geophysical and Sampling Survey 1974/17: North Sea: Geochemistry (1/Oct/1974 to 19/Oct/1974)

This British Geological Survey (BGS) marine geophysical and sampling survey took place in October 1974 in the North Forties-South Viking area aboard the Royal Research Ship RRS John Murray. The purpose was to evaluate gamma spectrometry technique in an area where no solid outcrop would occur. This provided an opportunity to gather data in an area with no previous coverage. A total of 1290 km of data were collected in a grid of 13 survey tracks. Sea floor data were collected using a echo-sounder and a transit sonar. Subsurface data were gathered using a suite of seismic instruments (airgun, sparker, pinger). Analogue data were collected and paper records were generated. Sea-bed samples and cores were collected using shipek grab and gravity corer. The data are archived by BGS. Technical details of the survey are contained in BGS Technical Report WB/74/15C.
