CRAMP Rapid Assessment. Sediments

Bulk sediments are collected from each site surveyed. Transects within each site are selected for sediment collection based on habitat type. Bulk sediments are collected from at least one transect of every habitat type represented at each RAT site.

Habitat types include:

  • colonized hardbottom (>10% coral cover)

  • uncolonized hardbottom (<10% coral cover)

  • submerged algal vegetation (>10% algal cover)

  • unconsolidated sediments (sand or silt)

Replicate samples were collected from each of the 94 stations representing each of the 54 CRAMP/RAT sites. No sediment was found along the transect at the 10 m site at Kamalō, Moloka’i. Depths ranged from 1 m to 23 m.
