Bryde's whale calls from the Panama Basin, recorded during the JC114 cruise
收藏资源简介:
Bryde's whale calls observed using JC114 OBS deployment in the Panama basin (Jan.-Feb. 2015) In file "matfiles.zip" are individual Matlab files for each whale call that was detected, picked and located in Tary et al., 2024. Each file include: - dath: cell array of time series of all OBSs working at the moment the call was recorded - hdr: header corresponding to the data in dath, including the sampling rate (st) for each instrument, the data starting time (tbeg) for each instrument, the list of instrument names (sta, NG: OBSs from North Grid, VA: Vertical Array of hydrophones in North Grid), the list of instruments with P-wave picks (stap), times of P-wave picks (ppicks), weights for each P-wave pick (weightsp), and picking uncertainties for each P-wave pick (punc). The Matlab function: seeVAevents.m, can be used to visualise the Matlab files with whale calls. Additional files: - NonLinLoc_locations.txt: whale call locations obtained using NonLinLoc (see Tary et al., 2024). Columns are as follows: YYMMDD / HHMM / SS.SS / Latitude (DMS) / Longitude (DMS) / Depth (km) / RMS (s) / Horizontal error (km) / Vertical error (km) - hypoDD_relocations.txt: whale call locations obtained using NonLinLoc followed by hypoDD (see Tary et al., 2024). Columns are as follows: Event ID / latitude / longitude / depth (km) / YYYY / MM / DD / HH / MM / SS.SSS - instrument_positions: positions of the OBSs and the hydrophones of the vertical array. Columns are as follows: instrument names / latitude / longitude / depth below sea surface (km) - whale_call_labels.xlsx: Matlab file names corresponding to whale track numbers described in Tary et al., 2025. Whale track number 0 corresponds to no labels assigned. - jc114_whale_calls: xml files including meta-data for the submitted dataset (in the style of ezEML files from edirepository.org) For further details: Hobbs, R., and Peirce, C.
