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.

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.

This continent-wide network is positioned to observe significant meteorological events and increase our understanding of the climate of the Antarctic surface. Researchers utilize the AWS network to observe and learn about the Antarctic in a warming world. Given the duration of the AWS program and maintaining AWS sites for many years, numerous studies have been conducted on the surface climatology of regions of the continent, such as the Ross Ice Shelf. This climatology also aids in other studies, like winter warming events.\n\nThe Antarctic Automatic Weather Station network provides a greater understanding of the surface meteorology and climatology throughout the continent of Antarctica. The AWS network spans the Ross Ice Shelf, Ross Island, West Antarctica, East Antarctica, and the South Pole. Since some of the AWS have been working for over 30 years, we can begin to understand the climate over many regions of Antarctica."},"location":{"line":"true","lat":"-77.8419","lon":"166.6863"},"media":{"url":"\/files\/2020-01\/Penn_IMG_1314_800px.jpg"}}]}}

Upcoming Live Event from McMurdo Field Station with teacher Bill Henske

Beacon Valley Team
Dates

Join PolarTREC Tuesday, 24 January at 9:00 am Alaska time (10 am Pacific, 11 am Mountain, 12 pm Central, 1 pm Eastern), for a live PolarConnect event with educator Bill Henske and the Dry Valleys Ecosystem Study team. Bill will be joined by members of "Team Wormherder" to discuss the research and fieldwork involved in the project, and what it's like to live and work in Antarctica. As part of the McMurdo Dry Valleys Long-Term Ecological Research (MCM LTER) Program, Bill's presentation will focus on research being carried out in the McMurdo Dry Valleys of Antarctica. The Dry Valleys represent a region where life approaches its environmental limits. The overarching goal of this long-term research project is to document and understand how ecosystems respond to environmental changes.

The live PolarConnect event with educator Elaine Krebs and the IceCube and Askaryan Radio Array 2022 team on January 18, 2023 is now archived. The IceCube Neutrino Observatory is located at the South Pole and records the interactions of a nearly massless sub-atomic messenger particle called the neutrino. 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.
