常规海况下星载散射计获取海面风场具有较高的精度，且广泛应用于目前海洋、气象和气候学研究与业务化应用当中。然而，高风速海况下，波浪破碎对散射计回波散射强度产生影响，导致按照常规方法获取德风场与真实风场存在偏差。本文针对波浪破碎下的散射计风场反演算法开展研究，聚焦地处西风带的南极绕极流(ACC)海域，通过引入海面白冠覆盖率与风速经验关系模型，利用神经网络法，构建了波浪破碎影响下的散射计风场反演新方法，
Five vegetation quadrats were designed and established in the area of Ny-(A)lesund, Svalbard in July, 2011 and another four were constructed there in 2012.They are 1 m× 1.5 m in size and occupied the
微型浮游动物在海洋食物网中扮演着重要角色.于2012-2013年夏季在南大洋-印度洋海域利用稀释培养实验进行了微型浮游动物对浮游植物的摄食现场实验研究.结果表明,微型浮游动物的摄食率为0.26d-1-1.30d-1,浮游植物的生长率为0.36d-1-0.61d-1,浮游动物日摄食量占浮游植物现存量的23％-73％,对浮游植物初级生产力的摄食压力也较大,为75％-123％.由此推论,在南大洋-印度洋
The metazoan meiofauna in the Arctic Chukchi Sea were collected from the 7 shallow waters stations (depths ranges 46-52 m) and 5 deep sea waters stations (depths ranges 393-2300 m) in the Chinese four
2010年7月在白令海区获得10个站位的大型底栖生物样品,经鉴定共记录大型底栖动物90种,率属于59科78属,其中环节动物41种,节肢动物23种,软体动物16种,棘皮动物3种,其它动物7种.研究区域大型底栖动物平均密度为984个/m2,平均生物量为1207.1 g/m2.密度以环节动物为主,生物量以棘皮动物为主.研究区域大型底栖动物优势种为尖锥虫(Scoloplos armiger)、太平洋方甲涟
Penguins play important roles in the biogeochemical cycle between Antarctic Ocean and land ecosystems.The emperor penguin Aptenodytesforsteri, however, is usually ignored because it breeds in fast sea
