The Years of the North Atlantic Humpback Whale
Entry ID: seamap274

Abstract: The Years of the North Atlantic Humpback whale (YoNAH) is the broadest-ranging, most intensive study ever undertaken of a marine mammal species. Standardized sampling protocols were used in all areas to minimizes biases due to sampling. The YoNAH project collected photographs of individually distinctive natural markings, genetic samples and behaviour data on humpback whales in the North Atlantic ... View entire text

Purpose: The YoNAH project is a unique research program utilizing photo-identification techniques and molecular genetics to conduct an intensive survey of the population ecology of humpack whales throughout their known North Atlantic range. This internationally collaborative project involves scientists from seven nations. YoNAH's vast database supports a wide range of scientific investigations and also ... View entire text
