A comparative study made on the amount of sea salt (dominantly NaCl) deposited on Macquarie Island due to atmospheric precipitation. It is found that the scavenging of solid salt particles alone cannot account for all the salt budget over certain areas of the Island. It is considered that sea spray droplets carried aloft by winds and scavenged by precipitation in the immediate vicinity of the shoreline is responsible for this deficit. The fields in this dataset are: Site details: Altitude, Distance from west coast and Mean annual precipitation. Chemical component Bubble size diameter Mass of salt particle Dry salt particle radius Number of equivalent days of continuous precipitation Site: Plateau, Wireless Hill, Isthmus Dry salt particles Sea spray droplets Total fallout
