Note: the attached documents reflect the overview of our proposed research submitted for translation in February 2017, including our time in Quttinirpaaq national park (Lake Hazen). Specifically to this proposal with the NRIB for work at the McGill Arctic Research Station on Axel Heiberg Island dates in/out are July 25 to 27 2017. The two field team members will be Dr. Sherry Schiff and Dr. Michael English.

Field Dates: July 6th to July 28th, 2016
Status of Research:
Background information and original objectives can be found in our initial permit (QUT-2015-18618). We had a productive second field season in 2016 and were able to collect a large amount of data geared to supplement and expand on preliminary findings from our first field season in 2015. Lake Hazen receives the majority of its inflow from a number of glacial rivers and minor amount from terrigenous subcatchments. As such, our past field season provided a better understanding as to how these glacial rivers influence the distribution and dynamics of carbon (C) containing chemical species in the Lake Hazen watershed. In particular, we aimed to describe transformation of dissolved organic and inorganic carbon (DOC and DIC), using stable and radioactive isotopes, from a number of glacial river discharges into Lake Hazen. We developed an in depth dataset that will allow for the comparison and contrast of different glacial river systems flowing into Lake Hazen that may illustrate spatial and temporal variabilities in C inputs and perhaps shed light on the underlying mechanisms responsible for these differences. Collection of samples at similar sites in 2017 will add to the Lake Hazen long-term database, as well as contribute to a better understanding of the export of nutrients from this high-arctic environment. Our objectives for 2017 are similar to that of the original proposal, but looking to focus more on understanding the source of dissolved and particulate carbon within Lake Hazen, obtaining a better estimate of DOC contribution and age from glacial rivers, and quantifying a hydrological mass balance for Lake Hazen. In order to accomplish this, we propose a couple small changes to our original permit.

Proposed Amendments & Rationale:
• Extension of Permit Expiration Date
Our permit expired on July 31, 2016. Our proposed field season would run from July 6th to July 28 2017. We request an extension of the permit to encompass this time.
• Helicopter Time in the Park
In previous years we have worked closely with Dr. Vincent St. Louis to compile helicopter time based on an amendment in his field permit (Permit Number: QUT-2015-18575), although this summer our field seasons will not overlap. This summer we would be happy to coordinate with other research groups at the Lake Hazen base camp and Parks Canada staff to most efficiently implement our helicopter time and minimize any disturbance to the landscape.
