Photo by Sandra Thornton.\n\nAs ocean temperatures warm, in particular the shallow Chukchi Sea, many organisms may spread into Arctic waters. Some of these present significant threats to human and ecosystem health, such as harmful algal bloom (HAB) species (commonly called red tides). The potent neurotoxins that these species produce can affect marine mammals, seabirds, and other resources critical to subsistence harvesters.\n\nAt the same time, little is known about the present and future risk from toxic algae to humans in the Pacific Arctic region. This study will be the first to document the current distribution of highly toxic HAB species over large spatial scales within the Alaskan Arctic and will provide estimates of areas at high risk of toxicity now and in a warming future. The hypothesis underlying this project is that HABs in Alaskan Arctic waters are not only transported from the south through Bering Strait but are now originating locally on the Chukchi shelf due to warming temperatures, circulation dynamics, and water mass structure. These factors influence bloom magnitude, duration, toxicity, and recurrence. This will be addressed through a joint physical-biological field and laboratory program to study the relationship between HAB species distribution\/dynamics and the physical environment of the Chukchi Sea region.\n\nThe distribution of HAB species on the Chukchi shelf will be mapped in relation to hydrography and circulation, including a comprehensive survey of the Alaskan Coastal Current which transports the warmest water in the Chukchi Sea. A range of molecular and physiological tools will be used to investigate the origin, connectivity, and fate of HAB populations in the region. Sediment profiling will establish a historical record of blooms along the major transport pathways to the western Arctic. This information will be used to generate conceptual models of the origin, transport, and fate of HABs in the Chukchi Sea region."},"location":{"line":"true","lat":"56.9073","lon":"-178.1395"},"media":{"url":"\/files\/2020-01\/Bartlett_Brown_EvieWorking_800px.jpg"}},{"date":"<time datetime=\"2022-07-10T12:00:00Z\">10 July 2022<\/time>\n - <time datetime=\"2022-08-05T12:00:00Z\">5 August 2022<\/time>\n","text":{"headline":"<a href=\"\/expeditions\/effects-of-lemmings-on-the-arctic-tundra-ecosystem\" hreflang=\"en\">Effects of Lemmings on the Arctic Tundra Ecosystem<\/a>","text":"<strong>Dates:<\/strong> <time datetime=\"00Z\">10 July 2022<\/time>\n - <time datetime=\"00Z\">5 August 2022<\/time>\n <br \/>\n<strong>Location:<\/strong> Utqia\u0121vik, Alaska <br \/>\n\nLemming in Utqia\u0121vik, Alaska\n\nThe team plans to use observations and experiments and models to understand how the fluctuations in the numbers of small mammal herbivores on the tundra, both within and between years, affect tundra ecosystem function (such as the abundance of different types of plants, the quality of plant litter and nutrient cycling) and energy balance.

Inuit Qaujimajatuqangit (IQ), or Inuit knowledge literally translates in Inuktitut to mean \u201ca way of knowing\u201d and science are two ways of knowing the natural and physical world. Both have a useful, complimentary, and insightful methodology. Holders of IQ and scientists are learning to better understand the benefits of each knowledge frame, though seldom do they fully appreciate the discipline or practice of the other, and even less often do they actively integrate these two knowledge approaches. More importantly, future generations of children from Inuit and other First Nations groups rarely have a welcoming entre into scientific studies through their oral tradition of IQ. Similarly, students in countries adopting scientific study or STEM as part of their core curriculum, rarely get introduced to IQ or other knowledge perspectives until pursuing more advanced studies in social science. This study will bridge these systems of thought and knowledge models through educational settings, by establishing baseline content during workshops with Inuit and non-Inuit elders, hunters and experts representing both knowledge frames as they apply to the study and knowledge of the narwhal.

IceCube searches for neutrinos from the most violent astrophysical sources: events like exploding stars, gamma ray bursts, and cataclysmic phenomena involving black holes and neutron stars.\n\nThe IceCube Neutrino Observatory is a powerful tool to search for dark matter, and could reveal the new physical processes associated with the enigmatic origin of the highest energy particles in nature. In addition, IceCube studies the neutrinos themselves using the 100,000 neutrinos detected per year produced by cosmic rays in the atmosphere. Their energies far exceed those from accelerator beams. IceCube encompasses a cubic kilometer of instrumented ice, and is the largest detector by volume ever built.\n\nThe fully built ARA project, also located at the South Pole, will have an effective volume 100 times bigger than IceCube. The trade off is that it is only capable of observing radio waves from extremely high energy neutrinos, a million times more energetic than the neutrinos produced by cosmic rays in the atmosphere.

These ice-free areas of Antarctica display a sharp contrast to most other ecosystems in the world, which exist under far more moderate environmental conditions. The perennially ice-covered lakes, ephemeral streams and extensive areas of exposed soil within the McMurdo Dry Valleys are subject to low temperatures, limited precipitation and salt accumulation. The dry valleys represent a region where life approaches its environmental limits, and is an end-member in the spectrum of environments included in the LTER Network.\n\nThe overarching goal of MCM LTER research is to document and understand how ecosystems respond to environmental changes."},"location":{"line":"true","lat":"-77.5","lon":"163"},"media":{"url":"\/files\/2020-01\/Dickerson_P1200001%20_800px.jpg"}},{"date":"<time datetime=\"2022-10-29T12:00:00Z\">29 October 2022<\/time>\n - <time datetime=\"2022-12-10T12:00:00Z\">10 December 2022<\/time>\n","text":{"headline":"<a href=\"\/expeditions\/antarctic-automatic-weather-stations-2021\" hreflang=\"en\">Antarctic Automatic Weather Stations 2021<\/a>","text":"<strong>Dates:<\/strong> <time datetime=\"00Z\">29 October 2022<\/time>\n - <time datetime=\"00Z\">10 December 2022<\/time>\n <br \/>\n<strong>Location:<\/strong> McMurdo Station, Antarctica <br \/>\n\nThe team raises meteorological instrument equipment onto the Sabrina Automatic Weather Station (AWS), Antarctica.

Student applications are now open for the Juneau Icefield Research Program 2023 field season. Application materials are due December 18th for priority consideration. Applications submitted after the due date will be considered on a rolling basis.

The Juneau Icefield Research Program (JIRP) offers a summer field course for students interested in undergraduate-level Polar sciences with a focus on glaciology, climate processes, glacial geomorphology, periglacial ecology, and interactions between these systems. JIRP is also appropriate for graduate students with limited experience in these topics. Students learn through academic and research interactions with rotating faculty from around the world. Workshops, field trips, and lectures focus on the primary topics listed above but also cover Alaskan geologic history, geomatics, and remote sensing, geophysics, scientific literacy, and science communication. In addition, the program capitalizes on the expertise of rotating faculty members to cover current questions in science.
