The connection suggested by Mann and Drinkwater (1994), between the NAO
and the growth and survival of cod, was as follows. When the NAO was strongly
positive, cold northwest winds over the Labrador Sea caused anomalously cold
water on the Labrador Shelf and abnormally large areas of ice coverage. During
spring, this water mass moved slowly south. Melting ice led to anomalously low
salinity in the surface waters over the Grand Banks and the volume of cold water
in the intermediate layer was greater. Hence, conditions on the Grand Banks were
unfavorable for the growth and survival of cod larvae.

Koneksi yang disarankan oleh Mann dan Drinkwater (1994), antara NAOdan pertumbuhan dan kelangsungan hidup cod, adalah sebagai berikut. Ketika NAO adalah kuatpositif, dingin barat laut angin laut Labrador disebabkan anomalously dinginair pada Labrador rak dan es cakupan area yang abnormal besar. Selamamusim semi, air ini massa bergerak perlahan-lahan Selatan. Pencairan es menyebabkan anomalously rendahsalinitas di perairan permukaan atas Grand Banks dan volume air dinginlapisan menengah adalah lebih besar. Oleh karena itu, kondisi di tepi Grand yangtidak menguntungkan untuk pertumbuhan dan kelangsungan hidup larva cod.
