在西北印度洋，中国大洋94航次正在开展水体调查，重点关注人类活动和气候变化双重影响下海洋环境 变化和缺氧现象驱动机制、生物多样性演变和适应机制等科学问题，为该区域生物多样性保护提供有效 的科学支撑。 2月13日起航的中国大洋95航次考察队，正在驶向西南印度洋执行多金属硫化物资源勘探和环境基线调 查任务，将为我国硫化物矿区资源评价和环境评估工作提供重要数据资料。该航次首席科学家陶春辉表 示，海底硫化物的勘探与环境评价是一个国际难题，我国采用自主研发的海底钻机、深海硫化物孔域原 位观测探测系统、硫化物厚度探测系统等高新技术，将对矿区的海底硫化物资源量开展精细勘探。 在西北太平洋，中国大洋91航次在我国北京先驱公司多金属结核合同区开展了资源环境调查。目前，调 查已获取了合同区资源分布特征、合同区冬季环境参数，为未来采矿装备试验的环境影响评估工作提供 支撑。 新春佳节，在遥远的大洋上，依然有4支中国科考队在开展大洋考察。自20世纪70年代我国开展大洋科 学考察起，浩瀚无垠的大洋和奔腾汹涌的海浪就见证着我国在大洋科考领域取得的丰硕成果。 在西太平洋，搭载"蛟龙"号载人潜水器的"深海一号"船正在执行西太平洋科学考察航次， ...

央视网消息：2月18日，"蛟龙"号载人潜水器在西太平洋进行了2026马年第一潜。此次西太平洋科学考 察航次，由"深海一号"船搭载"蛟龙"号载人潜水器和无人遥控潜水器联合作业，标志着"一船双潜器"模 式进入业务化阶段。 ...

北京时间除夕，"蛟龙"号开展了其第419次下潜，也是本航次的第8次下潜，深度超过4000米。本航次是"蛟龙"号载人潜水器和无人遥控潜 水器常态化联合作业，标志着"一船双潜器"的模式进入业务化阶段。 央视网消息：自上世纪70年代我国开展大洋科学考察起，浩瀚无垠的大洋和奔腾汹涌的海浪就见证着中国在大洋科考领域取得的丰硕成 果。 新春佳节，在遥远的大洋上，依然有四支中国科考队在开展大洋考察。他们都取得了哪些新进展？一起去看一看。 在西太平洋，搭载"蛟龙"号载人潜水器的"深海一号"船正在执行西太平洋科学考察航次，将充分发挥"蛟龙"号的原位高精度探测优势，完 成热液区生态调查，并开展海洋地质、海洋化学、海洋生物、海洋物理等调查。 在西北太平洋，中国大洋91航次正在我国北京先驱公司多金属结核合同区开展资源环境调查，目前，已获取了合同区资源分布特征、合同 区冬季环境参数，为未来采矿装备试验环境影响评估工作提供支撑。 在西北印度洋，中国大洋94航次正在开展水体调查，重点关注人类活动和气候变化双重影响下海洋环境变化和缺氧现象驱动机制、生物多 样性演变和适应机制等科学问题，为该区域生物多样性养护提供有效的科学支撑。 目前，中国大 ...
