We present a high resolution sedimentary record of dinoflagellate cysts spanning the last ~ 900 years.
- •
Dinoflagellate cyst assemblages reflect past changes in SST, SSS and primary productivity in Effingham Inlet.
- •
Record of MCA, LIA and 20th century warming on the west coast of Vancouver Island.
