Virtual Base Camp

Expeditions by Year

Welcome to the Virtual Base Camp, the starting point for your exploration of the polar regions with PolarTREC teachers and researchers!

PolarTREC expeditions to the Arctic and Antarctica can be found here starting in 2007 to 2015. You can also access archived expeditions to the Arctic that took place through TREC in 2004-2006. Journals, photos, ask the team forums, and information about each expedition can be found by following the links to all the expeditions. Use the Expedition Search feature to narrow your choices or find a particular expedition or region. Use the Members feature to find teachers and researchers involved with PolarTREC expeditions.

A new feature to the Virtual Base Camp are Projects. Projects are expeditions that had teachers for more than one year. You can learn more about the science and see all the teachers and researchers involved in the research project over two or more years. You can also access all the related project resources (presentations, lessons, PolarConnect events, etc.) related to the projects.

United States
Dates:
6 June 2018 to 7 July 2018
Location:
Toolik Field Station, Alaska
What Are They Doing?
The goal of this expedition is to understand arctic terrestrial change by monitoring vegetation communities in northern Alaska associated with the International Tundra Experiment Arctic Observatory Network (ITEX-AON). The team will study environmental variability and increased temperature on tundra plant phenology, growth, species composition and ecosystem function. The ITEX network works collaboratively to study changes in tundra plant and ecosystem responses to experimental warming. The network monitoring sites are located across many major ecosystems of the Arctic. This project will provide urgently needed data critical to understanding the impact of multi-scale vegetation change on ecosystem function, namely land-atmosphere carbon and water fluxes and energy balance.

Dates:
24 June 2018 to 4 July 2018
Location:
Ship-based, Eastern Bering Sea
What Are They Doing?
Eastern Bering Sea (EBS) jellyfish populations have fluctuated dramatically during the past three decades. When jellyfish populations are high, they likely have major impacts on the Bering Sea food web. This project will estimate the age structure and age-specific abundances of the predominant jellyfish in the Bering Sea, Chrysaora melanaster, in order to understand how their population size changes with time. The ultimate goal is to estimate the reproductive capacity and success of this jellyfish in relation to climate variability and to investigate the potential for jellyfish population increases to become a recurring pattern in the Bering Sea under future climate scenarios. This will in turn enable forecasting of jellyfish abundance and their predatory impacts in the Bering Sea ecosystem.

Cabrillo Marine Aquarium
Los Angeles, CA
United States
Dates:
15 March 2015 to 30 April 2015
Location:
Research Vessel Nathaniel B. Palmer
What Are They Doing?
The movement of warmer ocean water through or around relatively cooler ice sheets has the potential to lead to increased melting of the ice sheets. This project will determine the potential vulnerability of key ice streams to the infiltration of warmer ocean water and whether this could explain any of the observed thinning of the ice sheet. It will provide important information about a particular section of the East Antarctic Ice Sheet and therefore will be critical for future ice sheet models and investigations into the ice sheet's contributions to sea levels.

Location:
Western Arctic Ocean, aboard the USCGC Healy
What Are They Doing?
Many trace elements are critical for marine life and therefore influence the functioning of ocean ecosystems and the global carbon cycle. Some trace elements are also of concern as contaminants, while others, together with a diverse array of isotopes, are used to assess modern-ocean processes and the role of the ocean in past climate change. Despite the recognised importance of trace elements and isotopes in the ocean, our ability to exploit knowledge of their attributes is limited by uncertainty about their sources, sinks, internal cycling and chemical speciation. GEOTRACES now fills this critical gap with knowledge of the marine biogeochemical cycles of trace elements and their isotopes at an unprecedented scale. Scientists from approximately 35 nations have been involved in the programme, which is designed to study all major ocean basins over the next decade. Much more information on details of the project can be found at the [GEOTRACES website](http://www.geotraces.org/). The...

Dates:
1 November 2015 to 6 December 2015
Location:
McMurdo Station, Antarctica
What Are They Doing?
Humans have occupied the McMurdo Sound for over a hundred years. Early visitors had little impact on the region, but starting in the late 1950’s year-round, permanent buildings were established at McMurdo Station. Over the years thousands of humans have visited this area and have changed the landscape. Under its obligations to the Antarctic Treaty, the United States maintains a long-term monitoring program designed to track the environmental conditions in and around the station. Each year, the research team conducts environmental monitoring and chemical, physical, and biological sampling in and around McMurdo Station. They collect samples from both marine and terrestrial habitats as measures of human impact. They take the samples back to the lab to look for contaminants. The results of this research help document and minimize the impacts of future science and support operations in Antarctica. This information can be used to inform management decisions in and around McMurdo...
