Sea otter disturbance in eelgrass beds in Southeast Alaska
This dataset is composed of counts of the number of pits that were dug by sea otters, as well as a qualitative assessment of the primary and secondary sediment grain sizes (most common and second most common). The number of pits and sediment grain size were quantified at intertidal sites that includ...
