A 9.4 mm armored cable with two single mode and two multimode fibers was deployed in the cross shore coastal ocean from Duck, NC. DAS and DTS were used to measure bottom temperature and strain and connect those measurements to surface signatures of coastal hydrodynamics measured by camera and radar.
