Data supplement to: Defratyka et al (2021); Ethane measurement by Picarro CRDS G2201-i in laboratory and field conditions: potential and limitations. https://doi.org/10.5194/amt-2020-410

Sara Defratyka, Jean-Daniel Paris, Camille Yver Kwok, Daniel Loeb, James France, Jon Helmore, Nigel Yarrow, Valérie Gros & Philippe Bousquet
Ethane can be used as a tracer gas to distinguish methane sources, both at the local and global scale. Currently, ethane can be successfully measured using flasks or dedicated in-situ analyzers. In our study, we consider the possibility of using the CRDS Picarro G2201-i instrument, dedicated to isotopic CH4 and CO2, for suitable measurements of ethane:methane ratio in mobile field, near-source conditions. Our work was divided into three steps. First, laboratory tests were run to...

Forecasts, neural networks, and results from the paper: 'Seasonal Arctic sea ice forecasting with probabilistic deep learning'

Tom R. Andersson & J. Scott Hosking
This dataset encompasses data produced in the study 'Seasonal Arctic sea ice forecasting with probabilistic deep learning', published in Nature Communications. The study introduces a new Arctic sea ice forecasting AI system, IceNet, which predicts monthly-averaged sea ice probability (SIP; probability of sea ice concentration > 15%) up to 6 months ahead at 25 km resolution. The study demonstrated IceNet's superior seasonal forecasting skill over a state-of-the-art physics-based sea ice forecasting system, ECMWF SEAS5, and...

Polarimetric ApRES data on a profile across Dome C, East Antarctica, 2013-2014

Hugh Corr, Catherine Ritz & Carlos Martin
The radar data collected in 2013-2014 at Dome C, East Antarctica, aims to understand bulk preferred crystal orientation fabric near a dome. We measure changes in englacial birefringence and anisotropic scattering in 21 sites along a 36 km long profile across Dome C. These optical properties are obtained by analysing radar returns for different antenna orientations. More details can be found in Ershadi et al, 2021. Funding was provided by BAS National Capability and IPEV...

Not all species were monitored for the entire duration of the study, and the number of observations per species ranged from 21 to 133.

Evidence for an Allee effect in a declining fur seal population

Rebecca Nagel, Claire Stainfield, Cameron Fox-Clarke, Camille Toscani, Jaume Forcada & Joseph Hoffman
Allee effects play an important role in the dynamics of many populations and can increase the risk of local extinction. However, some authors have questioned the weight of evidence for Allee effects in wild populations. We therefore exploited a natural experiment provided by two adjacent breeding colonies of contrasting density to investigate the potential for Allee effects in an Antarctic fur seal (Arctocephalus gazella) population that is declining in response to climate-change induced reductions in...

GPS and Time-Depth Recorder tracking of common and Brunnich's guillemots from five colonies around Iceland, June-July 2019-2021

Norman Ratcliffe & Anne-Sophie Bonnet-Lebrun
We tracked 94 common and 50 Brunnich's guillemots from five colonies around Iceland (Latrabjarg, Grimsey, Langanes, Skrudur and Papey) during late incubation and chick rearing from June to July 2019. We also tracked 5 common and 3 Brunnich's guillemots from Langanes during chick-rearing in July 2020 (GPS only). We used Pathtrack nanoFix GPS loggers to record locations every 3min and Cefas G5 TDR loggers to record depth every second. The tags recorded the birds' behaviour...

Diversification patterns in Boeckella

Claudia Maturana
Aim: We investigated evolutionary relationships and biogeographical patterns within the genus Boeckella to evaluate: 1) whether its current widespread distribution in the Southern Hemisphere is due to recent long-distance dispersal or long-term diversification; and 2) the age and origin of sub-Antarctic and Antarctic Boeckella species, with particular focus on the most widely distributed species: B. poppei. Location: South America, sub-Antarctic islands, maritime Antarctica, continental Antarctica and Australasia. Methods: To reconstruct phylogenetic patterns of Boeckella, we...
