Marine Science Students Learn About Estuaries
The marine science class visited Niumalu Beach Park, where Dr. Carl Berg
explained estuarine ecosystems and native Hawaiian plants adapted
to brackish water.
Students measured the salinity at various locations
using a refractometer and found it ranged from 11 ppt to 27 ppt (ocean
water is 35 ppt). The students also helped in the removal of invasive
red mangrove seedlings from the newly re-vegetated marsh.
