Thursday Evening January 23: Anchialine Ponds by Lorena Wada

Aloha Thursday Evening Patrons,

Just a reminder! On Thursday evening January 23rd, the UH Sea Grant Hanauma Bay Education Program continues its public outreach series at the City and County of Honolulu’s Hanauma Bay Nature Preserve.

Thursday January 23,

Anchialine Ponds

Lorena Wada, Assistant Field Supervisor, Pre-listing and Listing Program, U.S. Fish and Wildlife Service

An anchialine pond is a landlocked body of water with a subterranean connection to the ocean. Anchialine ponds are a feature of coastal aquifers which are density stratified, with the water near the surface being fresh or brackish, and saline water intruding from the coast below at some depth. Water levels in anchialine pools often fluctuate with tidal changes due to the coastal location and the connection with the ocean. Anchialine pools are extremely common worldwide especially along neo-tropical coastlines where the geology and aquifer system are relatively young, and there is minimal soil development. Such conditions occur notably where the bedrock is limestone or recently formed volcanic lava. Ecological studies of anchialine ponds frequently identify regionally rare and sometimes endemic species living in them. In Hawai‘i, the pools are home to mostly the ‘ōpae‘ula (Hawaiian shrimp, Halocaridina rubra). To learn more show up next Thursday!   

As always, these events begin at 6:30 p.m. on Thursday evening in the theater at the Hanauma Bay Education Center.  Events are free and open to the public, with no charge for parking after 5:30 p.m.  We hope to see you on Thursday evening!  These programs are supported and funded by the City and County of Honolulu Department of Parks and Recreation.
