*** Availability of Seismic Data - Until the date that Canada
submits its extended continental shelf limits to the Commission on
the Limits of the Continental Shelf (by December 6, 2013), the
seismic data will not be released to other researchers except by
mutual consent of both GSC and USGS. After that date and up to
December 6, 2016, if the data have not been publicly released,
researchers interested in the data for scientific purposes can
submit a request to Natural Resources Canada (Geological Survey of
Canada, (GSC)) to obtain copies of the data. Upon consultation with
USGS about use of the data, GSC should not unreasonably withhold
permission to use the data as long as it is for scientific purposes
and involves collaboration with GSC or USGS in their use and
publication of results. The data should be fully publicly released
with no restrictions on its use after December 6, 2016. Seismic
data include seismic reflection and refraction data collected using
equipment from Louis S. St. Laurent. Until public release, the
official copy of these data are held at NRCan, Earth Sciences
Sector. After public release, the data will be available through
NRCan, Earth Sciences Sector. *** Availability of Singlebeam
Echosounder Data - Data outside of the Canadian 200-nm limit are
available through the Department of Fisheries and Oceans. Data
inside the 200-nm limit are considered proprietary under release
policy of the seismic data (see above). Until public release, the
official copy of these data will be held at DFO, Canadian
Hydrographic Service (CHS). After public release, the data will be
available through CHS. *** Availability of Other Data - Other
data collected during the LSSL cruise, such as navigation, gravity,
velocimeter profiles, CTD casts for water velocity, and ice imagery
are considered supporting data that are included in cruise reports
and other documentation as public information. Theyare not
necessarily formally released but will be supplied upon request to
either GSC or CHS.
