Abstract

Dimethylsulphide (DMS) has been implicated in climate change as a possible negative feedback to global warming, and several Models have been developed that simulate the production of DMS in the marine environment. The focus of this study is to improve the nitrogen based Gabric Model, using field data collected during the Southern Hemisphere First Marine Aerosol Characterisation Experiment (ACE-1) in the Southern Ocean in 1995. Two Model Runs (Series A and B) were carried out with six simulations of varying biotic and abiotic inputs applied over the voyage transect (41–48°S), reflecting Model default values or field values from the experiment. The abiotic inputs were time-step, dissolved dimethylsulphoniopropionate (DMSP) and DMS, and the biotic nitrogen inputs were from phytoplankton, bacteria, zooflagellates, large protozoa, micro and mesozooplankton. The focus of the abiotic assessment was nutrient (nitrate) uptake and dissolved DMSP and DMS output. Model output of the biotic compartments was assessed f...
利用基于氮的流动网络模型和ACE-1的现场测量,研究了南大洋的二甲硫化物产量
二甲基硫化物(DMS)作为对全球变暖的一种可能的负反馈与气候变化有关,已经开发了几种模型来模拟海洋环境中DMS的产生。本研究的重点是利用1995年南半球第一次海洋气溶胶表征实验(ACE-1)在南大洋收集的野外数据,改进基于氮的Gabric模式。两次模型运行(系列A和B)在航行样带(41-48°S)上进行了六次不同生物和非生物输入的模拟,反映了模型默认值或实验的现场值。非生物氮输入主要为时间步型、溶解型二甲基磺酰丙酸(DMSP)和DMS,生物氮输入主要为浮游植物、细菌、鞭毛虫、大型原生动物、微型和中浮游动物。非生物评价的重点是养分(硝酸盐)吸收、溶解DMSP和DMS输出。对生物隔间的模型输出进行了评估。
