Analysis methods: ----------------- Salinity samples are collected in glass bottles and analyzed on Guildline model 8410 Portasal Salinometers which are standardized with IAPSO standard seawater. Nutrient samples are analyzed frozen using a Technicon AAII auto-analyzer following methods described in Barwell-Clarke and Whitney (1966). References: 1. Carpenter, J.H. 1965.
