新华社“雪龙”号７月２１日电（记者 璩静）７月２０日至２１日，中国第五次北极科学考察队乘坐“雪龙”号极地科考船在北纬７０度、西经１６２度左右的海域遇到浮冰带，这也是本次北极科考起航后首次遇到浮冰。

    ２０日下午１４时起，“雪龙”号向北行驶，正前方的海面上逐渐出现大片白色浮冰，一条绵延几十公里的浮冰带延伸到天际线尽头。在海水和海风雕琢下，白色浮冰看上去冰清玉洁，而水面下却透着悠悠蓝冰。大的浮冰有足球场般大小，面积小的只有一两平方米。

    20 th at 14 within，“photo”, driving to the north，The sea front gradually appeared large white ice，A few kilometers stretching the ice with extended to end skyline。In the waters of the sea breeze and carve，White ice look Edward Chen，And under the water appearing however long LanBing。Big ice sheet is a football field size，The area is small only one or two square meters。

    首次看到浮冰，很多第一次参加极地科考的队员都很兴奋，毕竟从来没有在茫茫大海上看到这么多的冰块，大家争先恐后地跑到视线最广阔的六层驾驶室拍照留念。与队员相比，正在值班的大副朱利却不敢有丝毫大意，他一直盯着海面，不时举起望远镜观察冰情和水道情况，指挥“雪龙”号尽可能避开坚硬大块的浮冰。

    First see ice，Many first time to join the polar expedition players are excited，After all, never in the boundless sea of see so much ice，Everyone to run their view of the broad six floors takes a cab。Compared with players，Is the chief officer on duty but can't have no the Julius，He was staring at the sea，Sometimes raise telescope and waterways theory，command“photo”As far as possible, avoid hard chunks of ice。

    漂浮在湛蓝大海上的冰块固然美丽，但会在风和洋流的影响下不断漂移，威胁到科考队员的海洋调查作业。在浮冰密集的海域，科考队员进行海洋物理、化学、生物、地质等调查采样时，连接入海仪器的钢缆一旦被浮冰卡住或缠住，极易导致钢缆断裂、仪器损坏，甚至人员受伤，十分危险。

    Floating in the sea of blue on ice is beautiful，But will the wind and ocean currents in under the influence of the drift constantly，Threats to the expedition to Marine research work。In the dense ice waters，An expedition on offshore physics、chemical、biological、Geology, as well as the investigation and sampling，Connect the spokes of the instrument once ice stick or garment，Vulnerable to wire fracture、Instrument damage，Even injuries，Very dangerous。

    ２０日晚２０时左右，“雪龙”号进入浮冰非常密集的海域，浮冰密集度已达７０％至８０％，大量随波逐流的浮冰密密麻麻地将“雪龙”号团团围住。越往北走，浮冰越多且厚度逐渐增大，此时船速已降至四五节。２２时，“雪龙”号到达作业站点，中甲板作业区的队员反复确认周围没有浮冰后才把采水仪放入水中。在后甲板作业区内，作业班长与驾驶台经过多次沟通，在“雪龙”号船体向东稍稍移动后，见缝插针地找到一块水域，把用于采泥的箱式取样器和重力取样器分别放入水中。

    20 day night at about 20，“photo”Number into the ice is very intensive waters，Ice concentration has amounted to 70% from 80% to，A lot of drift ice will be sucked“photo”Surrounded by number。The head north，The more ice thickness and increased gradually，This time ship speed has been reduced to four or five section。22 when，“photo”Th to work site，Working in the middle of the team confirmed no ice around again and again before the collecting water meter in water。In the deck working areas，Monitor and silently homework after many communication，in“photo”Hull, east after a move，To find a piece of TDD waters，For in the mud box sampler and gravity sampler respectively in water。

    整个午夜，在船舱内都能听见船体与冰体碰撞时发出的“嘎吱嘎吱”声，船体也持续不规律地晃动。船长王建忠说，冰区航行最重要的就是要避免浮冰对船体的损伤，要根据浮冰密集度选择安全航速，同时要绕开大冰或用船头挤开浮冰。作为我国极地科考唯一的破冰船，“雪龙”号能以１．５节航速连续冲破１．１米厚的冰层前行，所以目前遇到的浮冰不会损伤船体。

    The midnight，In the compartment in can hear hull and ice body a collision“Creak on”sound，Hull also continues to not regular shaking。The captain WangJianZhong said，The most important apple voyage is to avoid the ice on the hull damage，According to the ice concentration select safe speed，And at the same time around big ice or with the bow to crowded open ice。As our country polar expedition only icebreaker，“photo”Can, in 1.5 1.1 meters thick speed continuous break the ice on，So are currently having the ice will not damage the hull。

    从目前卫星云图显示的海冰分布情况来看，第五次北极科考队作业区的浮冰密度较往年严重一些，但总体上仍属于常态。

    Satellite cloud pictures show from the current situation of sea ice distribution，The fifth the arctic expedition of precipitation ice density is ever serious，But overall, the still belongs to the normal。

    “在风力和海流影响下，北冰洋浮冰密集区每刻都在变化，一些以往没有浮冰的海洋调查站位都遭遇了浮冰，给下一阶段作业带来困难。”第五次北极科考队领队杨惠根说，“目前，考察队一方面细化了各项安全作业措施，另一方面也根据冰情对部分站位进行调整，力争寻找一些浮冰较少、相对开阔的水域，确保考察任务圆满完成。”

    “In the wind and ocean currents affect，Arctic sea ice concentration areas every moment changes，Some previous no ice ocean survey stations were encountered ice，To the next stage work difficult。”The fifth the arctic expedition leader YangHuiGen said，“At present，On the expedition team detailed the homework all safety measures，On the other hand also according to the theory of some stations adjustment，Strive to find some ice less、Relatively open water，Ensure that investigation mission accomplished。”
