Transport of Alaskan Dust into the Gulf of Alaska and Comparison with Similar High-Latitude Dust Environments
Transport of Alaskan dust into the Gulf of Alaska and comparison with similar high-latitude dust environments. An airborne flux of the micronutrient iron, derived from dust originating from coastal regions may be an important contributor of iron to the Gulf of Alaska's (GoA) oligotrophic waters...
