基于培养数据，研究了雨水引起的表层海洋浮游植物生物量（FE 1）和群落生长速率（U1）的变化。结果表明，大气湿沉降（AWD）（即，AWD‐NP）在很大程度上取决于表层沃茨的营养盐浓度和原地浮游植物生物量。FE 1和U1与海水营养物的量呈正相关（即，CE 1）在广泛的营养状态下被发现，这允许估计AWD-NP相对于现存量和再循环海洋生产。FE 1-CE 1模式的应用表明，AWD-NP与东海N-15技术估计的新产量相当。
The rainwater‐induced change in phytoplankton biomass (FE1) and community growth rate (U1) in surface oceans is examined based on the incubation data. The results indicate that new production (NP) stimulated by atmospheric wet deposition (AWD) (i.e., AWD‐NP) is strongly dependent on the nutrient concentrations and in situ phytoplankton biomass of surface waters. A positive relationship of FE1 and U1 against the amount of seawater nutrients (i.e., CE1) is found over a wide range of trophic states, which allows for estimating AWD‐NP relative to standing stock and recycled oceanic production. Application of a FE1 ‐ CE1 model shows that AWD‐NP is comparable to the new production estimated by the N‐15 technique in the East China Sea.
