Workshop 3: March 26 – 28, 2019 | Transformation and Transport of Elements and Compounds from Terrestrial to Aquatic Systems

Juneau, Alaska

This workshop is the third in the Coastal Rainforest Margins Research Network (CRMRN) series and will focus on soils and landscapes of the Coastal Temperate Rainforest (CTR) of the North American Pacific coast. The coastal rainforest margin of the Northeast Pacific is an area of intense tectonic, volcanic, and glacial history. The goal of this workshop will be to explore a framework to unify approaches to understanding how the landscape evolution of the region has resulted in soil and regolith patterns across diverse landforms. This foundation will provide landscape models for measurement and prediction of the elemental composition of soil landscapes and the resulting internal transformation and export of byproducts of biological production and soil weathering.


We are seeking participants in earth sciences (geology, soil, and geochemistry) to join the CRMRN steering committee to share information and data on coastal rainforest soils, define future paths for collaboration in coastal rainforest earth science, and work to integrate earth science information, knowledge and models with aquatic and marine initiatives within the network.


  • Review existing models of landform evolution and explore evolving models across the CTR;
  • Compile geologic and soil information into an integrated data structure to enhance modeling;
  • Explore mineralogical models of soil formation from varying parent materials and their relationship to pore waters;
  • Map relationships between landscape patterns and biogeochemical transformation and transport;
  • Establish collaboration across the CRMRN and the earth science community (Earthcube, Critical Zone, etc.)

Workshop 2: January 31 – February 2, 2018 | Marine-Terrestrial Interactions in the Coastal Temperate Rainforest Domain

Applications are now closed.

During this second workshop we will bring together a select group of oceanographers, biogeochemists, biologists, modellers and others interested in processes occurring at the land-sea interface in temperate regions. Although the workshop will focus heavily on the Pacific Coast, our findings are expected to have applications to temperate coastal rainforest domains globally.

Through this multi-disciplinary forum we aim to evaluate the current state of the knowledge of the terrestrial-marine system in the PCTR with respect to five key topics:

  1. Physics – freshwater controls of coastal hydrodynamics;
  2. Biochemistry – micro and macronutrient subsidies and their bioavailability to marine ecosystems; carbonate chemistry;
  3. Food webs – contributions and pathways of freshwater & terrestrial subsidies to marine food webs;
  4. Estuaries – the land-sea interface and role of estuarine ecosystems in modifying terrestrial outputs;
  5. Drivers of change – e.g., land use and climate.

Each topic will be introduced by key speakers, followed by discussion to define scope, discuss the current state of knowledge, distill and summarize data gaps, and identify future research directions. Our goal is to solidify a scientific community and build a research agenda on processes acting across temperate rainforest coastal margins.

Workshop 1: February 8–10, 2017 | Aquatic Carbon Biogeochemistry of Coastal Temperate Rainforests


Thanks to all those who joined us in Seattle for the inaugural workshop of the  Coastal Rainforest Margins Research Network!

This was the first of 5 annual workshops that will synthesize knowledge and address information gaps regarding the flux of water, carbon and nutrients from coastal watersheds to nearshore marine ecosystems.

A select group of hydrologists, aquatic biogeochemists, and others interested in processes occurring across the land-freshwater-ocean continuum discussed:  

  • the current state of knowledge of freshwater carbon biogeochemistry along the land-water continuum of the Pacific Coastal Temperate Rainforest and;
  • solidified a scientific community to build a research agenda on processes acting across temperate rainforest coastal margins into the future.
