Wave Glider Surfs Across Stormy Drake Passage In Antarctica（图）
wave glider surfs stormy drake passage antarctica
2017/10/24
The Southern Ocean is key to Earth’s climate, but the same gusting winds, big waves and strong currents that are important to ocean physics make it perilous for oceanographers.Instead their job is inc...
Cdrake: dynamics and transport of the Antarctic circumpolar current in drake passage
Antarctic circumpolar current dynamics and transport
2015/7/15
The Southern Ocean is especially sensitive to climate change, responding to
winds that have increased over the past 30 years (Thompson and Solomon,
2002) and warming at about one degree per centur...
High-Resolution Underway Upper Ocean and Surface Atmospheric Observations in Drake Passage: Synergistic Measurements for Climate Science
Ocean Surface Atmospheric Observations
2015/7/15
This article highlights recent and ongoing studies that analyze in situ underway upper ocean and surface atmospheric observations from frequently repeated transects by the Antarctic Research and Suppl...
Monitoring Drake Passage with elephant seals: Frontal structures and snapshots of transport
Monitoring Drake Passage elephant seals
2014/4/18
Conductivity–temperature–pressure satellite relay data loggers (CTD-SRDLs) were attached to southern
elephant seals (Mirounga leonina) on the island of South Georgia. During the animals’ migration th...
Antarctic Polar Frontal Zone from Australia to the Drake Passage
Antarctic Polar Frontal Zone Australia Drake Passage

North-south temperature sections drawn from historical XBT observations averaged over various longitude bands are compared with sections drawn from existing hydrographic data. Corresponding features i...
Variability of Deep Flow in the Drake Passage from Year-Long Current Measurements
Deep Flow Year-Long Current Measurements Drake Passage
2009/3/7
To investigate the reasons for the wide variation in previous estimates of transport of the Antarctic Circumpolar Current through the Drake Passage, an analysis of the spatial and temporal variability...
Structure and Transport of the Antarctic Circumpolar Current at Drake Passage from Short-Term Measurements
Antarctic Circumpolar Current Short-Term Measurements Drake Passage
2009/3/7
Three-week average speeds from an array of current meter moorings which spanned Drake Passage were used in conjunction with geostrophic calculations to estimate the short-term transport of the Antarct...
The Nature of the Poleward Heat Flux Due to Low-Frequency Current Fluctuations in Drake Passage
Poleward Heat Flux Drake Passage Low-Frequency Current Fluctuations
2009/2/16
Values of poleward heat flux due to low-frequency current fluctuations in Drake Passage are presented for 19 long-term current meter records obtained during 1975, 1976 and 1977. Most of the measuremen...
Currents and Temperatures as Observed in Drake Passage During 1975
Currents and Temperatures Drake Passage
2009/2/13
Current and temperature records from 10 meters on six year-long moorings deployed during February 1975 in Drake Passage are examined and discussed in the context of hydrographic data from that area. T...
A linearized baroclinic instability model is applied to the Drake Passage area. The predictions of the model are found to be in good agreement with observations. Temporal and spatial scales are predic...
The Net Transport of the Antarctic Circumpolar Current through Drake Passage
Net Transport Drake Passage Antarctic Circumpolar Current
2009/2/8
Estimates of the net transport through Drake Passage are made for three periods during which the year-long DRAKE 79 current meter array spanning the Passage was in operation. Relative geostrophic shea...

Cyclonic Ring Drake Passage
2009/2/7
An equatorward meander in the Antarctic Polar Front at Drake Passage was observed to amplify and pinch off during January and early February 1979, forming a cold-core. cyclonic current fins with a rad...
Monitoring the Transport of the Antarctic Circumpolar Current at Drake Passage
Antarctic Circumpolar Current Drake Passage
2009/2/6
Data from an extensive moored instrument array and three hydrographic cruises are used to calculate a time series of the net transport through the upper 2500 m of the Drake Passage. The baroclinic geo...
