Detailed Description

Two scientists work to identify change in the density and size distribution of mussels (Mytilus trossulus) in mussel beds. Long-term data collected are used as an indicator of mussel prey availability for various predators, including Sea Otters, Black Oystercatchers, sea ducks and sea stars.

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and describe mussel sampling and observations conducted in the northern Gulf of Alaska. This dataset consists of six comma separated files (.csv): 1) mussel sampling site layout information, 2) mussel counts for mussels greater than 20 millimeters in a quadrat, 3) mussel size measurements for mussels greater...

Evidence of increased mussel abundance related to the Pacific marine heatwave and sea star wasting Evidence of increased mussel abundance related to the Pacific marine heatwave and sea star wasting

Mussels occupy a key middle trophic position in nearshore food webs linking primary producers to predators. Climate-related environmental changes may synergistically combine with changes in predator abundance to affect intertidal ecosystems. We examined the influence of two major events on mussel (Mytilus trossulus) abundance in the northern Gulf of Alaska: the recent Pacific marine...
