Abstract:
Data collected in July, 2016 aboard the R/V Oceanus using an underway flow-through system. For detailed information regarding this system, refer to Burt et al. (2018) and Burt and Tortell (2018). The primary dataset, particulate backscatter (bbp), is presented in two formats. 'Binned' data refers to measurements that have undergone regular processing techniques, namely minute-binning and median filtering. Important metadata, including ships position, salinity, and chlorophyll, are all minute-binned. 'Raw' data refers to measurements not binned or median-filtered, which are higher-resolution (1 Hz, or per-second), and include a number of large 'spikes'. The height of each individual spike ('spikeheight') is also given. Raw bpp data is accompanied by concurrent measurements of particulate absorption at the 656 nanometer wavelength (ap656). Data from the ships acoustic doppler current profiler (ADCP) are also given, which includes vertical profiles of ADCP amplitudes (in decibars, extending from 9-147 meters depth in 2 meter bins) measured every 2 minutes. For more information regarding the specifics of this data, please refer to Burt and Tortell (2018).
