Erratum to: Characterizing the Relative Contributions of Large Vessels to Total Ocean Noise Fields: A Case Study Using the Gerry E. Studds Stellwagen Bank National Marine Sanctuary

摘要

A revised version of Table 4 is presented to correct conversion errors in the originally published table. In the corrected table, coarse estimates of the relative contributions of different sampled vessel types to the low-frequency (71-141 Hz) band with the sampled region in 2006 were derived by first converting average source levels estimates (total power in the 70 Hz band) for vessels of each type from decibels to watts. Average power per vessel type (watts) was then multiplied by the total number of hours spent by vessels of each type in the sampling region in 2006 to get an estimate of the total power generated by each type over the course of the year (watt hours/year).
