Hi! I’m a climate scientist trying to visualize the signal from a lot of noise. My research interests coincide with disentangling patterns of climate change from climate variability using data-driven methods, especially in the Arctic. I also spend a lot of time thinking about improving science communication and accessibility through storytelling with engaging visualizations.
Antarctic: Sea-Ice Concentration/Extent/Thickness
Current Antarctic sea ice extent (NSIDC, DMSP SSM/I-SSMIS F-18) in addition to climatology (blue, 1981-2010) and 2 standard deviations from the mean (updated 5/3/2024)[Special (temporary) graphic to monitor the ongoing record low] Antarctic sea ice extent for each year from 1979 to 2024 (satellite-era; NSIDC, DMSP SSM/I-SSMIS). 2024 is shown using a red line (updated 5/3/2024).[Special (temporary) graphic to monitor the ongoing record low] Antarctic sea ice extent for each year from 1979 to 2024 (satellite-era; NSIDC, DMSP SSM/I-SSMIS). 2023 is highlighted with a yellow line. 2024 is shown using a red line (updated 5/3/2024).Antarctic sea ice extent anomalies for each year from 1979 to 2024 (satellite-era; NSIDC, DMSP SSM/I-SSMIS). Anomalies are calculated using a 5-day running mean from a climatological baseline of 1981-2010. 2024 is shown using a red line (updated 5/3/2024).Antarctic sea ice extent anomalies stretching from January 1979 to present day (satellite-era; NSIDC, DMSP SSM/I-SSMIS). Anomalies are calculated using a 5-day running mean from a climatological baseline of 1981-2010 (updated 5/3/2024).Current regional Antarctic sea ice extents (NSIDC Sea Ice Index v3 : DMSP SSM/I-SSMIS F-18) for 2024 (red line) and for each year through the satellite era (blue [1979] to white [2023] lines). A map of the regions can be found at https://nsidc.org/arcticseaicenews/map-of-antarctica/. Graphic updated 5/3/2024.Daily rank for regional Antarctic sea ice extents (NSIDC Sea Ice Index v3 : DMSP SSM/I-SSMIS F-18) over the satellite-era (1979-2024). A map of the regions can be found at https://nsidc.org/arcticseaicenews/map-of-antarctica/. A rank of “1” is the lowest on record for a given region. A rank of “46” is the highest sea-ice extent on record for a given region. Graphic is updated for the ranks on 5/3/2024.Current regional Antarctic sea ice extents (NSIDC Sea Ice Index v3; DMSP SSM/I-SSMIS F-18) in addition to 2 standard deviations from the 1981-2010 mean (updated 5/3/2024).Current simulated (GIOMAS; Zhang and Rothrock, 2003) sea ice thickness and anomalies (1981-2010 baseline) updated for March 2024. For more information on this ice-ocean reanalysis dataset, see https://tc.copernicus.org/articles/16/1807/2022/.Latest GIOMAS model (Zhang and Rothrock, 2003) simulated sea ice volume (SIV) averaged for the Southern Hemisphere (Antarctic). Volume is averaged for each month from 1979 to 2024. Graphic updated through March 2024.Monthly Antarctic sea ice volume anomalies stretching from January 1979 to March 2024 (GIOMAS; Zhang and Rothrock, 2003). Anomalies are calculated from a climatological baseline of 1981-2010 (updated 4/24/2024).Since sea ice thickness observations are sparse, we utilize the GIOMAS model (Zhang and Rothrock, 2003) to visualize sea ice thickness averaged for each year from 1979 to 2023.
