Data for "Rapid seaward expansion of seaport footprints worldwide"

Data used in "Rapid seaward expansion of seaport footprints worldwide" (Sengupta & Lazarus, 2023: https://doi.org/10.31223/X5SD3T).

Data include five csv files:

'Sengupta_Lazarus_2023_F1_b' – total reclaimed area (km^2) in 2020, ranked by magnitude

'Sengupta_Lazarus_2023_F2_a' – normalised reclaimed area versus time for 68 seaports

'Sengupta_Lazarus_2023_F2_b' – series of ranks by different metrics: Lloyd's List 2020 (Lloyd's, 2021), total reclaimed area in 2020, area under normalised curves of reclaimed area through time, and coastal & cyclone hazard (Verschuur et al., 2023).

'Sengupta_Lazarus_rec_TEU_2011_2020' – data for container volume (in millions TEU) relative to reclamation area, 2011-2020; data for container volume sourced from UNCTD and the World Shipping Council.

'Sengupta_Lazarus_time_series_rec_data' – data (raw and smoothed) for seaport reclamation (km^2), 1990–2020

The method for calculating reclaimed area over time in Google Earth Engine (GEE) is described in Sengupta et al. (2023), and the GEE code is available here: https://github.com/dhritirajsen/Mapping_Coastal_land_reclamation

Code for plotting these data are available here: https://github.com/edlazarus/Seaports
