Wind-Forced ydrodynarnics and Their nteraction Fish and P ance: A Ti-Series An
We evaluated methods to measure simultaneously biological and physical properties essential for estimating short-term mortality of larval fish. We used the data to test Templeman's watermass exchange hypothesis and the associated safe-site hypothesis. Synoptic estimates of larval capelin (Malls...
