On the morning of Dec. 21, Hawaiian Volcano Observatory gas scientists use a FTIR spectrometer on the rim of Halema‘uma‘u crater. The FTIR measures the composition of the gases being emitted during Kīlauea Volcano's ongoing summit eruption by measuring how the plume absorbs infrared energy.

A helicopter overflight today (Dec 21, 2020) at approximately ~11:30 AM HST allowed for aerial visual and thermal imagery to be collected of the new eruption within Halema'uma'ucrater at the summit of Kīlauea Volcano. This preliminary thermal map shows that the new lava lake is 580 m (yd) E-W axis and 320 m (yd) in N-S axis.

Shortly after approximately 9:30 p.m. HST, an eruption commenced at the summit of Kīlauea Volcano. Red spots are the approximate locations of fissure vents feeding lava flowing into the bottom of Halema‘uma‘u crater. The water lake at the base of Halema‘uma‘u crater has been replaced with a growing lava lake.

The black oystercatcher, a keystone species in nearshore ecosystems, plays an important role in structuring nearshore systems and is highly susceptible to human disturbance. Current inventory and monitoring efforts may not adequately address the information needs for estimating long-term trends for this species.

Examining environmental deoxyribonucleic acid (eDNA) in water samples has demonstrated promise for identifying fish species present in water bodies. However, whether or not this same approach can be used to assess relative abundance, biomass, and species composition in large (greater than [>] 200-hectare) waterbodies is unclear.
