A. No: The number assigned to the seaport
B. Port name: Name of the seaport, either from World Port Index 2017 (https://msi.nga.mil/MSISiteContent/StaticFiles/NAV_PUBS/WPI/Pub150bk.pdf) or from Google Earth (closest city) 
C. Lat: Latitude coordinate of the port location
D. Lon: Longitde coordinate of the port location
E. Sediment type: The sediment type of the coast where the port is located (sandy, muddy, rocky)
F. Shelter condition:  The natural shelter condition of the port (open coast, rocky headland, behind natural barrier)
G. Breakwater length (m): Cross-shore breakwater length of longest breakwater
H: Coastline orientation: Coastline orientation with respect to North 
I: Sediment sources/sinks: The existence of rivers, estuaries and lagoons near the port with an indication whether these are updrift or downdrift or both wrt dominant wave direction
J: Coastal structures present: The existence and types of coastal engineering structures around ports (Shore protection structure = revetment, shore-parallel barrier, LST interuption structure = groyne, shore-normal structure)
K: Construction year: The year when port construction was finished and visible from satellite imagery (0 = <1984)
L: Extension year: The year when ports were extended and altered the coastal evolution trends (0 = no extension)
M: Postive wave power (m^2.5): Positive wave power wrt shore-normal
N: Negative wave power (m^2.5): Negative wave power wrt shore-normal
O: Number of images: The total number of satellite images used for analysis
P: Number of images per composite: The average number of image used per composite image
Q: Cumulative beach accretion area (km^2): The total beach accretion area since the start of time series analysis
R: Present beach accretion rate (km^2/yr): The present beach accretion rate
S: Cumulative beach erosion area (km^2): The total beach erosion area since the start of time series analysis
T: Present beach erosion rate (km^2/yr): The present beach erosion rate
U: Coastline accretion length (m): The total coastline length that experiences accretion
V: Coastline erosion length (m): The total coastline length that experiences erosion
W: Start of fitting (yr): The year of the first satellite imagery of sufficient quality
X: Gross area change (km^2): The total beach area change around the port P+R
Y: Net area change (km^2): The net beach area change around the port P-R
Z: Hotspots: Whether the port is ranked in the top 10% in terms of gross beach area change (1: Yes, 0: No)
