查询词典 Antarctica

Ross Island and Taylor Valley, Antarctica, are located on the juncture area between East Antarctica and West Antarctica and in the vicinity of Transantarctic Mountain . In this area, tectonism and magmatism have beeen active since Tertiary.

Australian Antarctic Division glaciology program head Ian Allison said sea ice losses in west Antarctica over the past 30 years had been more than offset by increases in the Ross Sea region, just one sector of east Antarctica.

The first procedure uses the GAMIT software to estimate parameters such as station position and orbital trajectory on a daily basis for a given 24-hour interval from the union of three data sets:(1) the campaign stations,(2) the continuously operating GPS stations in Antarctica,(3) long-running continuous GPS stations around Antarctica. In the second procedure, we combine the daily solutions with global GPS sub-networks (IGS1, IGS2, IGS3), which is provided by Scripps Institution of Oceanography, using the GLOBK software in a "regional stabilization" approach in order to estimate the positions and velocities.

数据处理分为两步，第一步：运用GAMIT软件进行单天解算，估计站位置、轨道等参数，其数据源主要有以下三类：(1) SCAR GPS观测站；（2）南极的连续跟踪站；（3）南极及其周边的部分IGS站；第二步：运用GLOBK软件加入SOPAC（Scripps Orbit and Permanent Array Center）的全球GPS子网（IGS1、IGS2、IGS3）进行全球网平差解算测站位置和速度。

ANTARCTICA follows man's thirst for exploration to the highest, driest, windiest, coldest continent on Earth. Audiences will marvel as they take a harrowing helicopter ride through icy crevasses and towering pinnacles; dive with the first humans to swim through a crystalline cavern submerged within a glacier; drill through centuries-old ice to unlock the secrets of Antarctica's past; and join a company of penguins in a graceful underwater ballet.
