Description

Updated monthly averaged fast-ice thickness on level first year fast ice in McMurdo Sound, Antarctica from a sea-ice monitoring station. Fast-ice thickness is derived from temperature measurements and manual drill hole measurements, and linearly interpolated to produce mid-month values. Do not use the original version (SIMS_thickness.xlsx) as an error has been discovered. SIMS_thickness_V2.xlsx is the corrected dataset. A description of the stations and the methods used can be found in Gough et al., 2012 and Richter et al. 2022.

Notes

Thermistor data collected in McMurdo Sound between 1996 and 2003 are available under \url{https://drive.google.com/drive/folders/1ooUH9dPvWT66afFC51Cb0JOHg66rn0sy}, data collected in 2002 and 2003 were part of the project ``Measurements and Improved Parameterization of the Thermal Conductivity and Heat Flow through First-Year Sea Ice'', OPP-0126007*. Data collected in 2009, 2010 and 2013 are available at the data repository PANGAEA \cite{gough2017data2009a, smith2017data2010, smith2017data2013, gough2017data2009b}. The thermistor data in McMurdo Sound collected after 2009 were collected with the following funding and logistics support: IRL Subcontract to the University of Otago (2010, 2011); University of Otago Research Grants (2010, 2011, 2014, 2015 (Event Manager: Inga Smith)); NIWA subcontract to University of Otago, ``Antarctic and High Latitude Climate'' (2013-2018); Contribution from MBIE-funded project ``Antarctic sea ice thickness: harbinger of change in the Southern Ocean'' (2013 (PIs: Pat Langhorne and Wolfgang Rack)); Contribution from MBIE-funded Curious Minds public engagement project ``Far from Frozen'' (2016, (leader: Craig Grant, Otago Museum)); US Fulbright Scholar Award (Cecilia Bitz, 2013); NZARI (2015 (PIs: Pat Langhorne and Craig Stevens), 2017, 2018 (PI: Greg Leonard)) Deep South National Science Challenge project TOPIMASI (2016-2018 (PI: Pat Langhorne)); Antarctic Science Platform Project 4 (Sea ice and carbon cycles) (2019, 2020 (Event Manager: Greg Leonard)); Marsden Fund project ``Supercooling measurements under ice shelves'' (2020 (PI: Inga Smith)).
