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.
