16. Going Forward: Mapping: - Compare recordable Hydro (SIMRAD CHIRP/Structure scan?) to ROV - Compare Hydro to density (1000 to 2000 micron sieve) Ecology: -Predators? - Fish stomach content -Seasonal growth/stacking -Caged growth? Chemistry: -Increase N+P Sampling -Increase TSD profiles and benthic pH Geology: -Cores to 1955 sand layer -Shell/fecal detritus/base layers -OTHER: …
