SCINI contained cameras and\nthrusters, and towed a sensor package consisting of a WET Labs fluorometer\n(ECO-AFL/FL) and a single-beam Biosonics 120 kHz DT-X echosounder. Visual\ntargets were identified to the lowest taxon possible; these observations were\nused primarily to verify classification of acoustic signals. The echosounder\noperated at a nominal ping rate of 1 ping s-1; however, this rate was\noccasionally adjusted if false bottom signals were observed. The general\nprofile of a dive included a surface transect of ~300 m horizontal distance,\nwhere the acoustic transducer faced downward, and also a dive to ~120 m if\nconditions allowed. Echogram data were saved to a depth of 500 m, and\nbackground noise was removed. Given the effective range of the transducer of\napproximately 100 m (resolving -80 dB targets), surveys characterized the\nupper 200 m of the water column.\n\ncdm_data_type = Other\nVARIABLES:\ngroup (unitless)\nsitenum (unitless)\nbin_depth (meters (m))\ndepth (m)\nsv_mean (per meter (m-1))\n https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_715715_iso19115.xml https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_715715/index.htmlTable https://www.bco-dmo.org/dataset/715715 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_715715.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_715715&showErrors=false&email= BCO-DMO bcodmo_dataset_715715
