Summer shows full of neat info: Tonight, meet Volcano's first anchialine pond
The summer After Dark in the Park program is rolling along at Hawaii Volcanoes National Park, with three events in July and August.
After Dark is presented on select Tuesdays at 7 p.m. in the Kïlauea Visitor Center Auditorium.
Tonight, the visitor center will unveil a new exhibit featuring a living anchialine pool. Learn about Hawaii's famous endemic shrimp, 'opae 'ula, from the pond guy, Scott R. Santos, Ph.D. Artwork for the display is by John Dawson.
Secondly, After Dark will welcome One Journey, LIVE in concert on the evening of July 19.
"This is sure to be a very popular program. I recommend coming early for good seats," said Park Ranger Dean Gallagher.
"And on Aug. 23, Hawaiian Volcano Observatory geophysicist Mike Poland will help us to make sense of the spectacular March Kamoamoa fissure eruption featured on news outlets throughout the world," he said.
Here's the program information:
-- Tonight: "Anchialine Pools: Uncovering the hidden secrets." Join Santos for an introduction to 'opae 'ula, or Halocaridina rubra.
The anchialine habitats of Hawaii are coastal features defined as "pools with no surface connection to the sea, containing salt or brackish water, which fluctuates with the tides" and are typically land-locked open pools and cracks such as those found in the Volcano park and along the Kona coast.
Although these habitats have been documented in many places, the Hawaiian Islands have the single largest concentration of anchialine pools in the world (approximately 520).
Unfortunately, many of these jewel-like pools have been modified or destroyed in the last 50 years either in the process of coastal development or by the introduction and spread of exotic species.
Understanding the biology of wildlife inhabiting anchialine habitats is paramount to developing sound management and conservation plans for these unique ecosystems. The living anchialine pool exhibit at the visitor center will feature native Hawaiian shrimp.
-- July 19:"One Journey: LIVE in Concert."
Brought together by their love of music, these are high school friends sharing a common journey. They consider themselves local and organically grown artists springing from the fertile district of Ka'u.
"Most have now graduated high school, and some soon to graduate, but all possess talent rarely found outside that of professional musicians," said Gallagher. "Striving to reach that perfect outcome as a local music group, bringing musical respect to Ka'u and the state of Hawaii.
"Come enjoy an evening of local music performed by One Journey -- winners of the statewide Brown Bags Band Competition."
Lead vocals: Dillin Ballo and Eunice Longakit. Music by Kasey Camba, David Ramones, Kiana Pascubillo, Rigiel Goralli, James (Kimo) Tyson and Moses Espaniola III.
"Beware: You may feel the urge to dance," said Gallagher. One Journey music CDs will be available the evening of the concert for purchase and autographs.
-- Aug. 23: "Kïlauea's March 2011 Kamoamoa fissure eruption: What happened, and what's next?"
On the afternoon of March 5, the floor of the Pu'u 'O'o eruptive vent on Kïlauea's east rift zone collapsed, and the summit caldera began to deflate rapidly as magma was drawn into the east rift zone near Napau Crater.
A few hours later, lava began to erupt between Napau and Pu'u 'O'o, marking the start of the Kamoamoa fissure eruption. The eruptive fissure reached a length of about 2 kilometers over the next several days, with activity jumping between different fissure segments and then gradually declining.
The eruption ceased on the night of March 9, and it was 17 days before lava again appeared on the surface of the volcano, filling the collapse crater at Pu'u 'O'o. The Kamoamoa fissure eruption was spectacular and caused major changes in Kïlauea's 1983-present east rift zone eruption.
Join Poland for a discussion of this fascinating event.
In addition to information about the eruption itself, Poland will describe activity that preceded formation of the fissure and Kïlauea's current status as the volcano continues to recover from the Kamoamoa eruptive event.
