Section 11: Time At-Sea/On-Land
This section will be shown when any amphibious species groups (i.e., sea turtles and pinnipeds) are selected in the Reference Section. Time at-sea refers to the duration of time in days that amphibious animals spend at sea, whereas Time on-land refers to the duration of time in days that amphibious animals spend on land.

Fields:

  • Time At-Sea Minimum
    TSL_TimeAtSeaMin(days):
    The minimum duration that the animal(s) spent continuously in the water(days).

  • Time At-Sea Maximum
    TSL_TimeAtSeaMax(days):
    The maximum duration that the animal(s) spent continuously in the water(days).

  • Time At-Sea Mean
    TSL_TimeAtSeaMean(days):
    The mean or average duration that the animal(s) spent continuously in the water (days).

  • Time At-Sea Median
    TSL_TimeAtSeaMedian(days):
    The middle value in the distribution of the duration at sea (days). If there is an even number of time at-sea values, it is the average of the two middle values.

  • Time At-Sea Mode
    TSL_TimeAtSeaMode(days):
    The most common time at-sea value; in the frequency distribution, the time at-sea with the greatest number of frequencies (days).

  • Time At-Sea Standard Deviation
    TSL_TimeAtSeaStdDev:
    To express the degree of dispersion in the time at-sea data, the standard deviation (square root of the variance) should be entered (days).

  • Time On-Land Minimum
    TSL_TimeOnLandMin(days):
    The minimum duration that the animal(s) spent continuously on land (days).

  • Time On-Land Maximum
    TSL_TimeOnLandMax(days):
    The maximum duration that the animal(s) spent continuously on land (days).

  • Time On-Land Mean
    TSL_TimeOnLandMean(days):
    The mean or average duration that the animal(s) spent continuously on land (days).

  • Time On-Land Median
    TSL_TimeOnLandMedian(days):
    The middle value in the distribution of time spent on land (days). If there is an even number of time on-land values, it is the average of the two middle values.

  • Time On-Land Mode
    TSL_TimeOnLandMode(days):
    The most common time on-land value; in the frequency distribution, the time on-land with the greatest number of frequencies (days).

  • Time On-Land Standard Deviation
    TSL_TimeOnLandStdDev:
    To express the degree of dispersion in the time on-land data, the standard deviation (square root of the variance) should be entered (days).
