This dataset contains ASCII files with hypocenter information, event times and magnitudes for 227029 micro-earthquakes with a magnitude range from -2.0 to -0.3 recorded from a 35-station seismic network located ~40 km upstream of the grounding line of Rutford Ice Stream, West Antarctica. For 87910 of these events, earthquake focal mechanisms (strike/dip/rake) are available. The seismic network, which recordings are the base for the event catalogue, broadly formed a rectangle with 1 km station spacing. Details on the station locations, instrument types and operation periods are included in these data files. The event catalogue encloses the geographic region between 084.142 to 083.760 degrees West and 78.204 to 78.113 degrees South. Events are located between 1.553 and 2.416 km depth. Recording took place between 20th November 2018 and 16th February 2019. The spatio-temporal arrangement of these micro-earthquakes can be used to characterize frictional properties at the ice-bed interface of Rutford Ice Stream. This work was funded within the BEAMISH project by NERC AFI award numbers NE/G014159/1 and NE/G013187/1. Seismic instruments were provided by NERC SEIS-UK (Loan 1017) and the Incorporated Research Institutions for Seismology (IRIS) through the PASSCAL Instrument Center at New Mexico Tech.

This dataset contains data on egg laying rate and site choice of Drosophila melanogaster (fruit flies). Data were collected from laboratory studies to investigate oviposition decisions in Drosophila melanogaster. We manipulated the social environment (flies kept in solitude, pairs, groups of four, or groups of eight) and observed egg locations over 24 hours to understand socially-driven changes in laying rates and site choices. These data were used in the model, to investigate whether location patterns differed significantly from a random null distribution. The model output list K (clustering preference) values produced from Kolmogorov-Smirnov tests run on each fly vial tested. All data were collected at the University of Leeds, besides data on maternity of eggs which were collected at the University of East Anglia.
