CRMRN scientists Bill Floyd and Brian Menounos will lead a joint $2.4-million research project between the University of Northern British Columbia and Vancouver Island University. Supported by the Hakai Institute, the project will focus on understanding the role of seasonal snow cover and glaciers in the hydrology of key watersheds along B.C.’s Central and Southern Coast.
Earlier this month, Floyd and his team installed two new weather stations in the Homathko and Kliniklini watersheds, which drain the biggest icefields in the province. Snow depth, weather and other data collected at these stations will be useful in improving climate models, flood and avalanche forecasting, and more. Check out all twelve locations in the High Elevation Weather Station Network and view real-time weather data on the Coastal Hydrology and Climate Change Research Lab website.
Coastal temperate rainforests of the world are linked to coastal oceans through the riverine flux of freshwater and terrestrial materials. The coastal temperate rainforest of North America is a global hotspot for carbon storage on land and carbon transport from land to sea, suggesting a potential hotspot for marine processing of terrestrial materials. This transport is variable at scales ranging from individual storm events, to seasons, to inter-annual climate anomalies, suggesting a land-ocean connection that may turn ‘on and off’ depending on climatic conditions. Since 2013, the Hakai Institute has been collecting year-round measurements of stream chemistry and discharge to the ocean in a Critical Zone Observatory consisting of seven small watersheds in the BC coastal rainforest. The dataset spans over 5 years and 3 climate anomalies (including the extreme El Nino year of 2015-2016).
Hakai seeks a post-doctoral fellow to analyze the stoichiometric relationships of freshwater nutrient exports as well as the dynamic coupling of nutrient export with weather and climate. The project aims to characterize the magnitude and dynamics of key fluxes in comparison to other regions of the world, through the lens of the receiving marine ecosystems. A complete biogeochemistry and hydrology dataset is available as well as rich ancillary data from the Observatory (e.g., weather stations, detailed soil mapping). The project is supported by Hakai Institute staff with expertise in data collection, data management, and data publishing. Collaborating scientists have expertise in biogeochemistry, hydrology, oceanography, microbial ecology, and landscape ecology.

ACRC postdoc Gavin McNicol will present an overview of recent work by the Coastal Rainforest Margins Research Network at the International Arctic Research Center in Fairbanks today, Thursday, July 19th 2018.
The Coastal Rainforest Margins Research Network (CRMRN) is currently accepting applications for the Scientist Exchange Program (SEP). The goals of this exchange program are to facilitate new collaborations between scientists; build new skills in field, laboratory, or statistical techniques; and assist with production of a deliverable product of the collaboration (e.g., manuscripts, data sets, research proposals).

They experimentally compared 11 different sensor brand and shield combinations to weather station data, and found that quite a few methods had a positive bias. It’s not something we haven’t known is a danger, but this is a nice way to standardize methods with some experimental backing behind it.
The longest running ecological plot network in the world looking at succession (1916-present) is in Glacier Bay, and now all available photographs have been compiled. They show a plant community evolving, from mostly bare rock to a variety of current states – spruce, alder, and willow, very different endpoints and something apparently unique to this portion of the bay.

A new map of both the range and decline of yellow-cedar has been published in Global Change Biology with help from researchers in Alaska, BC, and Washington. The high resolution range map stretches from northern California to southcentral Alaska, from sea level in the north to treeline in the south. The decline, now quantified at ~400,000 ha (about 7-8% of the total range area), covers southeast Alaska and central coastal BC, down to about 50 degrees north. It is primarily located in areas where the mean winter temperature is between -2 and +2 degrees C, as anticipated. The future climate of the region is expected to warm to that threshold by 2070 in most locations. However, there are a few places above that threshold where cedar is apparently healthy, probably due to a lack of cold winters to trigger the decline when there is no snow on the ground like the outside of Vancouver Island. How representative these sites are of the population at large needs to be further quantified. Next steps include a predictive model of decline and comparison of the decline maps to other sources of mortality data.
