海平面上升导致的欧洲洪灾八成可避免
海平面上升 欧洲 洪灾 可避免
2020/5/14
英国《自然·通讯》杂志6日发表的一项气候科学研究，欧盟委员会联合研究中心科学家发布的报告称：海平面上升导致预计会发生的欧洲洪灾中，至少有83%的洪灾可以通过抬高约三分之一的欧洲海岸线堤防而避免。超过两亿人的居住地距欧洲海岸线50千米以内，这段海岸线从大西洋东北部和波罗的海一直延伸到地中海和黑海。上个月一份来自欧洲科学家团队的报告指出，全球海平面曾在不到400年的时间里明显上升了12米至14米，其原...

研究揭示人类活动对海洋深远影响
人类活动 海洋 深远影响
2020/5/7
1平方米的区域就有190万个塑料微粒，这是有记录以来海底塑料微粒含量的最高值。格陵兰岛冰原每年平均损失2000亿吨冰，南极洲冰原损失1180亿吨冰。1亿吨冰足够填满40万个奥运会标准大小的游泳池。近日，刊登于《科学》的两项研究聚焦了覆盖地球表面3/4的“蓝色领土”。研究人员发现，这个幽深而富饶的“王国”正遭受着人类活动的强烈影响。其中一项研究的主要作者、英国曼彻斯特大学的Ian Kane说：“我们...

新AI算法能监测全球海洋塑料垃圾
新AI算法 全球海洋 海洋塑料垃圾
2020/4/24
英国《科学报告》杂志23日发表的一项环境学研究，英国人工智能团队报告了一种能检测海洋环境中大塑料（大于5毫米）漂浮垃圾带的新方法。研究人员利用欧洲空间局“哨兵2”号卫星数据，训练机器学习算法将塑料从其他材料中区分出来，平均准确率达86%，局部区域最高达到了100%。人类活动与垃圾排放，让大量塑料涌入海洋，如何将塑料从其它漂浮物中准确高效鉴别出来成为难题。鉴于漂浮物吸收和反射的可见光与红外光波长各有...

In October 2019, scientists froze a ship filled with equipment into Arctic sea ice with the intention of drifting across the Arctic Ocean for a full year, gathering data on polar atmosphere, ic...
根据英国《自然·地球科学》杂志20日发表的最新研究论文，欧洲科学家团队报告称，全球海平面在不到400年的时间里明显上升了12米至14米，其原因是大约14650年前，欧亚冰盖局部发生崩塌所导致。冰盖是覆盖着广大地区的极厚冰层的陆地面积，冰盖的建立、消亡、融水量，以及冰盖的分布范围和成分的变化，直接影响局部地区乃至全球的环境变化，这已得到海洋学和（古）气候学领域学者们广泛的认同。而末次盛冰期是地球上始...
