Assessing the environmental impacts of construction in Antarctica

[Excerpt] Introduction: The origin of the Environmental Impact Assessment (EIA) was in 1969, as part of the US National Environmental Policy Act which imposed the obligation of all federal agencies to evaluate the potential impacts of activities on the environment (Ortolano and Shepherd, 1995). Its emergence coincided with the recognition of the fact that human activities could lead to changes in the natural setting (Morgan, 2012). The EIA is a procedure to identify, predict, investigate, evaluate and mitigate impacts from activities that are likely to have substantial effects on the environment. The evaluation must happen during the design and planning phase and can be done in different approaches such as interaction matrices, prediction of impacts, investigation and decision-making by government agencies (Toro et al., 2013). Recognized and used by many countries, the EIA methods are based on systematic environmental studies, in addition to relying on the support of a public consultation to assess project execution (Jay et al., 2007). The EIA have contributed to monitoring the development of environmental protection projects, the implementation of environmental laws and mainly as an instrument that assists decision-making in several administrative spheres (Morgan, 2012).

BEDMAP2 - Ice thickness, bed and surface elevation for Antarctica - standardised data points

We present here the Bedmap2 ice thickness, bed and surface elevation standardised CSV data points that were used to create the Bedmap2 gridding products. The data consists of 25 million points coming from 68 individual surveys acquired in Antarctica. The associated datasets consist of: - Bedmap1 standardised CSV data points: https://doi.org/10.5285/f64815ec-4077-4432-9f55-0ce230f46029 - Bedmap3 standardised CSV data points: https://doi.org/10.5285/91523ff9-d621-46b3-87f7-ffb6efcd1847 - Bedmap2 statistically-summarised data points (shapefiles): https://doi.org/10.5285/0f90d926-99ce-43c9-b536-0c7791d1728b - Bedmap2 gridding products: https://doi.org/10.5285/fa5d606c-dc95-47ee-9016-7a82e446f2f2 This work is supported by the SCAR Bedmap project and the British Antarctic Survey's core programme: National Capability - Polar Expertise Supporting UK Researc

BEDMAP2 - Ice thickness, bed and surface elevation for Antarctica - standardised shapefiles and geopackages

We present here the Bedmap2 ice thickness, bed and surface elevation aggregated points and survey lines. The aggregated points consist of statistically-summarised shapefile points (centred on a continent-wide 500 m x 500 m grid) that reports the average values of ice thickness, bed and surface elevation from the full-resolution survey data and information on their distribution. The points presented here correspond to the additional points to Bedmap1 used for the gridding of Bedmap2. The data comes from 14 different data providers and 75 individual surveys. They are available as geopackages and shapefiles. The associated datasets consist of: - Bedmap1 statistically-summarised data points (shapefiles): https://doi.org/10.5285/925ac4ec-2a9d-461a-bfaa-6314eb0888c8 - Bedmap3 statistically-summarised data points (shapefiles): https://doi.org/10.5285/a72a50c6-a829-4e12-9f9a-5a683a1acc4a - Bedmap2 standardised CSV data points: https://doi.org/10.5285/2fd95199-365e-4da1-ae26-3b6d48b3e6ac - Bedmap2 gridding products: https://doi.org/10.5285/fa5d606c-dc95-47ee-9016-7a82e446f2f2 This work is supported by the SCAR Bedmap project and the British Antarctic Survey's core programme: National Capability - Polar Expertise Supporting UK Researc

BEDMAP3 - Ice thickness, bed and surface elevation for Antarctica - standardised data points

We present here the Bedmap3 ice thickness, bed and surface elevation standardised CSV data points that are used to create the Bedmap3 gridding products in addition to the previous data releases. The data consists of 50 million points acquired by 17 different data providers in Antarctica. The associated datasets consist of: - Bedmap1 standardised CSV data points: https://doi.org/10.5285/f64815ec-4077-4432-9f55-0ce230f46029 - Bedmap2 standardised CSV data points: https://doi.org/10.5285/2fd95199-365e-4da1-ae26-3b6d48b3e6ac - Bedmap3 statistically-summarised data points (shapefiles): https://doi.org/10.5285/a72a50c6-a829-4e12-9f9a-5a683a1acc4a This work is supported by the SCAR Bedmap project and the British Antarctic Survey's core programme: National Capability - Polar Expertise Supporting UK Researc
