Only very rarely has there ever been long-term (~1-year) imagery of hydrothermal vent sites, and even more rarely have images been streamed live.Yet, the information digital stills provide is crucial to understanding how these systems evolve and their linkages to biology: there is little information about how animal communities at vent sites change at temporal scales of minutes, hours, and days.
The digital still camera is a modified Kongsberg OE14-408 with strobes, and is capable of producing a high-definition still image every 1 second. The camera platform includes pan and tilt capabilities. In 2014, the CAMDSB303 system was installed at a diffuse flow site in the International District Hydrothermal Field within Axial Volcano’s caldera (Site MJ03C). It is perfectly situated to observe long-term changes of the macrofaunal communities at the 'El Gordo' vent. At MJ03C, there is also a cabled diffuse fluid sampler (RASFLA301) , a microbial DNA sampler (PPSDNA301), and mass spectrometer (MASSPA301) that allow, for the first time, time-series measurements of fluid, temperature, and chemistry correlated to imagery of changing animal and environmental conditions. The instrumentation will also yield information on the impact of flow perturbations associated with eruptive and seismic events on biological communities.
