Operating from the ship R/V Seward Johnson, JSL1 has two separate pressure hulls, can accommodate four people, and travels at a maximum speed of one knot. The front chamber contains a 5-ft-diameter sphere made of five-in thick, clear acrylic that provides a panoramic view for the pilot and one observer. The second chamber, the stern compartment, houses another crewmember and a second observer who has access to two side view ports and a video monitor. The JSL1 is equipped with an active sonar system and xenon arc lights which illuminate underwater scenes in "true color," resembling daylight conditions. It's also outfitted with exterior still and video cameras on an extendable platform, a hydraulic robotic arm, suction tube, claw, scoop, and sampling jars. The sub can be retrofitted with a wide range of additional equipment to best fit the research needs. The Johnson-Sea-Link I was retired in 2011 after the support ship the R/V Seward Johnson was sold to Cepemar Environmental Services of Brazil. sponsor: xlink: https://www.ngdc.noaa.gov/docucomp/08D95C427FB128479945893256DADE37 title: NOAA/OAR/OER - Ocean Exploration and Research (POC) |
