- Lime Kiln Point (wa100.dnr.wa.gov)
When you hear the word ‘kiln’ you probably think of hot flames and brightly colored pottery. What you may not know is that kilns are also used to make ‘lime’, an important ingredient for mortar and cement. Lime Kiln Point hosted a productive cement industry between 1860 and 1935, with workers laboring as much as ten hours a day at the kilns to produce thousands of barrels of lime per year. This popular 41-acre State Park is also home to an historic lighthouse that dates back to 1919. The lighthouse is still used for navigation by ships sailing through Haro Strait. The beautiful rugged coastline here makes Lime Kiln Point an excellent place—some say one of the best in the world—to watch orcas, gray whales, and porpoises during their yearly migration from May to September. Settle down at one of the viewing areas and enjoy the spectacle!
- Holocene sea-ice dynamics in Petermann Fjord in relation to ice tongue stability and Nares Strait ice arch formation (tc.copernicus.org)
The Petermann 2015 expedition to Petermann Fjord and adjacent Hall Basin recovered a transect of cores, extending from Nares Strait to underneath the 48 km long ice tongue of Petermann glacier, offering a unique opportunity to study ice–ocean–sea ice interactions at the interface of these realms. First results suggest that no ice tongue existed in Petermann Fjord for large parts of the Holocene, raising the question of the role of the ocean and the marine cryosphere in the collapse and re-establishment of the ice tongue. Here we use a multi-proxy approach (sea-ice-related biomarkers, total organic carbon and its carbon isotopic composition, and benthic and planktonic foraminiferal abundances) to explore Holocene sea ice dynamics at OD1507-03TC-41GC-03PC in outer Petermann Fjord. Our results are in line with a tight coupling of the marine and terrestrial cryosphere in this region and, in connection with other regional sea ice reconstructions, give insights into the Holocene evolution of ice arches and associated landfast ice in Nares Strait.
