attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv,.esriCsv,.geoJson
attribute NC_GLOBAL acquisition_description String Coral collections and spawning
Eight colonies of the brooding coral Porites astreoides were collected on
St. John, U.S. Virgin Islands (18.31384N, 64.76439W) on 22 June 2017. The
colonies were maintained in a shaded outdoor ambient seawater-supplied
aquarium. Corals spawned overnight 22-24 July and larvae were collected each
morning and maintained in 0.2m filtered seawater. On 25 July, larvae from all
colonies and spawning nights were pooled, and groups of 55 actively swimming
larvae were selected. Groups were randomly assigned to one of 9 light or 9
dark 140ml polyethylene chambers (preconditioned with reef water for one
month) filled with 0.7m filtered seawater (remove grazers, retains microbes).
Each chamber contained two preconditioned settlement surfaces: a clay stilt
(3.8cm diameter) and a red cable tie (10.2cm; chosen from previous findings,
Mason et al. 2011). Light chambers were transparent, allowing ambient light
ingress, while dark chambers were externally covered with black tape to
prevent light transmission.

Settlement experiments
Following larval addition, three light and three dark settlement chambers
were each affixed to a vertical pole deployed at three sites: Tektite Reef
(18.30962N, 64.72218W), Cocoloba Reef (18.31528N, 64.76065W), and a sand site
with no reef structure within 100m (18.31789N, 64.75059W) (Table 1). Sites
differ in biophysical habitat characteristics (Table 1) known to influence
soundscape properties (6). The experimental set-up included acoustic recorders
(SoundTrap ST-300, Ocean Instruments NZ), recording continuously at 48 kHz,
and temperature/light loggers (HOBO Pendant UA-002, Onset Corporation). The
chambers and instruments were secured 0.20.5m above the seafloor in 710m water
depth (see Figure 1C). Larvae were completely isolated within settlement
chambers, allowing exposure to ambient sounds (polyethelene plastics have high
acoustic transparency) while preventing exposure to other water-borne habitat
cues (e.g., reef water chemicals).
\tChambers were recovered after 62 hours and maintained in seawater tables
during the 6-hour processing period in which settled corals were enumerated.
Some actively swimming larvae were still present, suggesting that oxygen
remained sufficient for larval survival.

attribute NC_GLOBAL project String Coral Chorus
attribute NC_GLOBAL projects_0_acronym String Coral Chorus
attribute NC_GLOBAL projects_0_description String Coral reef ecosystems host some of the highest biodiversity of life per unit area on Earth and harbor about one quarter to one third of all marine animals. Reef-associated animals are a major source of protein for millions of people, and reefs offer shoreline protection and provide a significant source of tourism revenue, especially in developing countries. Factors that influence supply and settlement of young (larval) fish, coral, and associated animals can have large impacts on reef ecosystem and population structure, and learning more about these can help improve understanding of how to maintain the benefits provided by coral reefs. This study will lead to a detailed, mechanistic understanding of how young larvae use natural sounds to orient toward, locate, and select preferred settlement habitat. The approach will combine detailed field measurements and experiments to isolate key soundscape variables that impact coral reef larvae. 
For marine communities, such as those on coral reefs, factors influencing larval supply and settlement can have major impacts on community structure and population replenishment. There are now some indications that sound plays an important role in attracting larvae to suitable settlement habitat. There is little understanding of what soundscape habitat information is available to larvae and how differences and variability in sound can influence settlement. This project will include comprehensive experiments, environmental measurements, and modeling with the goal of understanding the role of sound in influencing larval recruitment and local biodiversity. The investigators will measure in situ settlement of larval fish and coral in relation to different soundscapes and habitat conditions in a marine protected area using traditional larval sampling methods, moored acoustic recorders, and a suite of environmental observations. Controlled and calibrated environmental playback experiments will isolate soundscape components and determine specific and fundamental acoustic cues larvae use to orient and settle. The spatial and temporal variability of soundscape cues and components across reef habitats will be established. Finally, the project will determine the relevant ranges of sound plumes that larvae may encounter through direct measurements of the sound fields of multiple reefs.
