Lingered iceberg along Dronning Maud Land coast from August 2012 to August 2014
This dataset provides the positions of icebergs in **_August 2012_**, **_August 2013_** and **_August 2014_** along the Dronning Maud Land coast. It also provides positions of lingered icebergs over five periods: 1. **August 2012** to **October 2012** (2 months) 2. **August 2013** to **October 2013*...

| Summary: | This dataset provides the positions of icebergs in **_August 2012_**, **_August 2013_** and **_August 2014_** along the Dronning Maud Land coast. It also provides positions of lingered icebergs over five periods: 1. **August 2012** to **October 2012** (2 months) 2. **August 2013** to **October 2013** (2 months) 3. **August 2012** to **August 2013** (1 year) 4. **August 2013** to **August 2014** (1 year) 5. **August 2012** to **August 2014** (2 years) These icebergs were identified by a human operator using Radarsat2’s ScanSAR Narrow images. Data are provided in point shapefile format. The attribute for each point are the bed elevation (meters above sea level) at the point position according to IBCSO bathymetry dataset (Arndt et al., 2013; “ibcso_b”) and the method used to determine the elevation (“ibcso_s”). If the first digit of “ibcso_s” is a 2, “ibcso_b” was acquired using multi-beam sonar, if the first digit is a 3 data were acquired using single-beam sonar, and if the first digit is a 6, data were interpolated. Each file is named after the date at which the iceberg were tracked. For example, icebergs lingered between August 2012 and October 2012 are stored in SIB_8_12-10_12_IBCSO.shp. Icebergs found in August 2012 are stored in SIB_8_12_IBCSO.shp. |
