在本届南极地球科学讨论会(1987年8月24—28日)期间及会后,南极研究科学委员会(SCAR)分别举行了南极地质制图学、火山岩地质及岩石学、南方高纬度新生代古环境演化、南极岩石圈结构与演化四个专家组正式会议.由于时间冲突,笔者未能参加古环境会议.制图会议对讨论会上展示并向SCAR提交的图件逐一审议.其中地质图均为小范围大比例尺图,如巴西提交的乔治王岛菲尔德斯半岛地形地质图(1∶1.5万);地球物理方面以航磁图为多;最引人注目的是大面积遥感图,利用卫(航)片经数据处理清晰地反映出地质构造或冰盖结构特征.会议着重讨论了今后几年计划实现的16幅图件(地质6、地球物理6、遥感3、水文1),其中主要有“南极地质全图”(1∶1千万,Tingey主编,“斯科舍弧构造图”(1∶3百万,J.W.Thomson主编),“罗斯海、威得尔海构造及地震剖面图”(比例尺未定,K.Hinz主编),“南极半岛地区地震剖面及地质图”(比例尺未定,C.O.Berbert主编)等.当讨论新遥感图件协调问题时,几家大公司代表就“LANDSAT”、“SPOT”、“AVHRR”等卫星及数据处理性能优劣争论激烈,并都希望由本公司承担这一任务.
During and after this symposium on Antarctic Earth Science (August 24-28, 1987), the Antarctic Research Science Committee (SCAR) held the Antarctic geological mapping, volcanic geology and petrology, the southern high latitude Cenozoic ancient Environmental evolution, the Antarctic lithosphere structure and evolution of the four expert group formal meeting due to the conflict of time, the author failed to attend the ancient environment conference.Combining meeting on the seminar presented to the SCAR submission of the map one by one of which the geological map are Large-scale small-scale maps such as the topography of the Phenomenon Peninsula of Princes Island in the island of Georgetown (1: 15000) submitted by Brazil; aeromagnetic charts in geophysics as much; most notable are large-area remote sensing maps, After the data processing, it clearly reflects the geological structure or the structural features of the ice sheet.The conference focused on the 16 pieces of plans (Geology 6, Geophysics 6, Remote Sensing 3 and Hydrology 1) planned to be implemented in the next few years, mainly including “Antarctic Geological Map” (1: 10M, edited by Tingey, “Skoches arc structure diagram” (1: 3 million, edited by JWThomson), “section of the Ross Sea and Widrnd Sea structures and seismic sections” (Undetermined scale, edited by K. Hinz) Antarctic Peninsula seismic section and geological map “(the scale is not determined, COBerbert editor), etc. When discussing the coordination of the new remote sensing map, several large companies on behalf of” LANDSAT “,” SPOT “,” AVHRR "satellites and data Deal with the merits of the controversial performance, and all hope that the company to assume this task.
