| Abstract: | The phenomena of near surface temperature maximum (NSTM) occurred continually in the Canada Basin from 2004, which is one of the responses to the rapid change of the arctic. The fine structures of the NSTM are studied using the CTD data by the third National Arctic Research expedition of China(CHINARE) and the joint west arctic climate study (JWACS) and the Beaufort Gyre exploration project (BGEP) and ITP18 data collected in 2008 in the Canada Basin. The vertical properties of the NSTM are related to the sea ice. In the sea ice covered area there is little difference of the NSTM. But the differences of the maximum of temperature and the vertical structures of the NSTM are obvious in the marginal ice zone and the open water. The maximum temperature and the corresponding depth are related to not only the period of the NSTM, but the latitude of stations. The higher the latitude, the deeper the corresponding depth of the maximum temperature of the NSTM. The annual period of the NSTM is shown by ITP data, which occurrs in summer and disappears in spring in next year. |
