新华社北京/"雪龙"号12月18日电 题：从探洋识冰到巡天瞰海！我国海洋卫星大显身手 新华社记者刘祯、顾天成 近日，执行中国第42次南极考察任务的"雪龙"号和"雪龙2"号在中山站成功完成物资卸运和人员登陆工作。协同卸货作业期间，"雪龙2"号为"雪 龙"号破冰引航。 在较为复杂的冰情下，"雪龙"兄弟探洋识冰，海洋监视监测卫星功不可没。记者从考察队和国家卫星海洋应用中心了解到，我国已建成由海洋水 色、海洋动力、海洋监视监测三大系列卫星组成的协同观测体系，11颗在轨卫星编织起全天时、全天候、全覆盖的"海洋感知网"，助力巡天瞰 海。 海洋监视监测卫星：名副其实的"海上千里眼" 南极科考，为什么"雪龙2"号可以判断乱冰区情况，确定最优破冰路线？ "哪怕是乌云密布、大雾弥漫甚至伸手不见五指的黑夜，海洋监视监测卫星也能穿透干扰、透过黑暗捕捉海面的细节。"指着5米分辨率、50公里 幅宽的高分辨率冰区卫星遥感冰情信息专题图，海洋监视监测卫星地面系统副总师安文韬十分自豪地告诉记者。 "海水呈绿色通常表明浮游生物繁盛，偏黄色则多由泥沙、悬浮物等导致。"海洋水色卫星地面系统副总师叶小敏的一句话，道出了海洋水色卫星 的"拿手绝活"。 ...

近日，执行中国第42次南极考察任务的"雪龙"号和"雪龙2"号在中山站成功完成物资卸运和人员登陆工 作。协同卸货作业期间，"雪龙2"号为"雪龙"号破冰引航。 在2030年前，海洋监视监测卫星将实现高、低轨卫星组网观测，提升对海上目标的实时跟踪能力，从而 为海上航行与作业安全保障、海洋权益维护提供更有力的技术支撑。 海洋水色卫星：细致入微的"健康观察员" "海水呈绿色通常表明浮游生物繁盛，偏黄色则多由泥沙、悬浮物等导致。"海洋水色卫星地面系统副总 师叶小敏的一句话，道出了海洋水色卫星的"拿手绝活"。 在较为复杂的冰情下，"雪龙"兄弟探洋识冰，海洋监视监测卫星功不可没。记者从考察队和国家卫星海 洋应用中心了解到，我国已建成由海洋水色、海洋动力、海洋监视监测三大系列卫星组成的协同观测体 系，11颗在轨卫星编织起全天时、全天候、全覆盖的"海洋感知网"，助力巡天瞰海。 三大系列卫星示意图。（国家卫星海洋应用中心供图） 海洋监视监测卫星：名副其实的"海上千里眼" 南极科考，为什么"雪龙2"号可以判断乱冰区情况，确定最优破冰路线？ "哪怕是乌云密布、大雾弥漫甚至伸手不见五指的黑夜，海洋监视监测卫星也能穿透干扰、透过黑暗捕 捉 ...
