A Millennium of Changing Environments in the Godthåbsfjord -bridging cultures of knowledge PhD student Ann Eileen Lennert 1 Greenland Institute of Natural Resources and Climate Research Centre, 2 1,2,3 Ilisimatusarfik, University of Greenland, 3The Arctic University of Norway, UIT The environment is under threat from so many directions that it is relevant to look in an interdisciplinary way. It is important to look at a whole spectra of interrelated fields, some obvious and some surprising with their relevance, when trying to understand environmental variations both in relation to pollution, climate change or just environments in general. Drawing interdisciplinary on social and natural sciences the project explores the links between variations in past and present sea ice, climate conditions, changing environments and human societies. Bridging cultures of knowledge the project aims to understand the environments in change through the eyes of the cultural landscapes, local knowledge, archives and together with marine geological history depositions and natural scientific data, reconstruct these lived environments with changing ice patterns, resources and changing human-environment relations in the Godthåbsfjord . It demonstrates how these interrelated fields can be used as proxies to prolong time series, better monitoring and the importance of how these different approaches and perspectives supplement each other in the understanding of environments in change. It amplifies the relevance for understanding climate and environments in change within the context of social and cultural change, changing settlement patterns and mobility, transformations in resource use, and local concerns over the development of large-scale industry. It is human interactions with nature, there lives that embed the cultural landscapes that together can be used as a proxy when looking back in time. Different cultures indicate different environmental setting, as the Norse preferring sea scapes, land for farming, and hunting of migrating seal at spring, whereas the Thule Culture and their winter settlements indicate, ice environments and ice margins favorable for hunting on ice or by kayak. Hunting structures indicate distribution of species and abundance, Movement and travel route indicate seasonal distribution of animals as caribou, migration patterns og marine mammals and fish, -these depend on specific environmental settings. Place names are typonyms, representing a knowledge that can be mapped in a cartographic space and seen as a basis of comparison to environmental phenomena's as climate change and environmental variations (Crate et al, 2009, Lennert, 2012, Lennert et al, 2015, Lennert, 2016a). Climate variations Animal diversity Stressfactors Oceanography Proxy Vegetation Animal behavior Time series movements, migrations, but this knowledge can also contribute with insight of given environmental settings, environmental variations and oceanographic settings. Behavioral knowledge of marine species as beluga whales can also contribute with how anthropogenic disturbances might influence certain species, how contaminants together with these might act as a cocktail that together with stress factors can result fatal impacts on not only the marine animals but also communities relying on them (Lennert 2012a, Lennert. 2016b) Contaminants Monitoring Local knowledge of animal behavior encompass knowledge of habitats, Ice distribution Salinity Sea temperature Ecosystems Tipping Points Interdisciplinary Glacier dynamics Ice patterns Animal migrations Melt off As marine geology, Archaeology represents a depositional history, indicate environmental settings and variations. Sedimentation layers can indicate both warm and favorable periods for growth as well as periods with cold and storminess. Macrofossils, as microfossils indicate environmental settings as well as variations through time. Here insects and plants being extremely sensitive to change. Bone material represent specific environmental settings. Together these two fields contribute with a coupling between different trophic layers and benthic pelagic systems, as well as top down and bottom up control. Furthermore middens can work as archives of species that indicate climate change and glacier melt water, as the mussel Mytilus Edulis (Lennert et al. 2016a, Versteegh et al 2012) Environmental variations To properly understand environmental variations through time observations based on daily interactions with the environments are of importance. Observations of fjords, coasts and their surroundings back in time. Local knowledge is an important element in understanding the changes and variations happening not only due to climate change and environmental variation but also to understand the fate of pollutants in this complex system. Hunters and communities in the arctic have through their lives have achieved to retain a unique knowledge, which makes them natural historians of their own land. Some travel in areas inaccessible to many and should be acknowledged as an important proxy to understand the interaction between elements, being natural or non natural in the arctic. Moving through the fjord knowledge here is shared about ice patterns, sound, glacier variations, taste of the sea, animal behavior, currents and recourse diversity through time. This knowledge not only maintained through indigenous life economies but also “modern” economies built on fisheries, local knowledge generated on communities relying of specific life sticks or people and scientist who have obtained knowledge through years of movement in a specific environment. (Lennert, 2016a, Lennert et al, 2016a) Productivity Understanding and knowledge of the complex environments seen in Arctic and its fjord systems only comes after many years of observations and monitoring. Long times series can be crucial to understand changes seen today, using the past to understand the present and eventually what scenarios we might see in the future when speaking of ecosystems, ice patterns, glacier terminus fluctuations, oceanographic settings among many. Archives encompass a large amount of historical data and proxies. Logbooks from ships, reports and observations can give a detailed picture of oceanographic settings, temperatures and ice distribution, trade list reflect distribution and abundance of different animal species, where they are found, size, age and among many. Old maps can show ice extent in winter, rivers not seen today og glacier terminus’s that has varied over time, areal photos from polar explorers, such as Lauge Koch and Knud Rasmussen as well as from World War II indicate glacial and ice variation currant in the 1930 warming period. Diaries can be seen as local knowledge sharing observations, interpretations of the whole spectra of interrelated fields (Lennert et al 2016b, Bjørk et al. 2012) Examples of some preliminary results looking at the 1930 warming; Fishermen and hunters dependent of marine animals are usually knowledge banks. A knowledge making them able to draw the bottom -Beluga and their behavioral patterns indicate the 1930 warming alreaddy was setting its footprints before 1920. topography of an area, as if measured by ships. Knowledge of distribution of fish and variations of these in relation to environmental settings. how change of sea currents, fresh water input from glaciers or disturbance of predators alter de distribution is a imperative, knowledge, not only to understand variations happening in the past, these seen today but also in relation to industry, mining, contaminants , regulations, quotas and anthropogenic disturbances of other kinds (Hall, 2013, Lennert et al 2016) whales -Areal photos show glaciers reteated further behind than today in 1930. -Trade lists show how Belugas move further north beginning 1920. -Old reports and diaries show an alternation of animals and sea ice before 1920. -Freeze degree model made from photos and satelite images (among other proxies) shows that only minor changes in surface water temp. and air temp. alter the extent of the winter ice edge in the Godthåbsfjord dramtically.. -Local knowledge and settlements indicate a change of both distribution of whales, and marine animals. -Beluga whales movement indicate sea currents of the Godthåbsfjord and how these change Contact: Email: Phone: Ann Eileen Lennert Environmental Anthropologist Greenland Institute of Natural Resources and Climate Research Centre anle@natur.gl +4790554526 References: Bjørk et al. 2012, An aerial view of 80 years of climate-related glacier fluctuations in southeast Greenland , NATURE GEOSCIENCE , VOL 5 , JUNE 2012, Hall, 2013 Recruiting the Visual: Knowing Our CommonPlace Towards an Encyclopedia of Local Knowledge , PhD Thesis, Lennert 2012, Settlement patterns in the Godthåbsfjord and the interactions between humans and ice (985-1350 A.D), Master thesis, Ilisimatusarfik & Greenland Climate Research Center., Lennert et al, 2015 Fangsthistorier oplevet og fortalt ud fra kulturlandskaberne: En rejse gennem tid og klimavariationer, Tidsskriftet Grønland 3/2015, Lennert, 2016a, What happens when the ice melts?
