Electronic Supplementary Material including: - Zircon U-Pb/Hf/O analyses of unknowns and calibration+validation material - Supplementary diagrams for data quality check - CL+BSE images of analyzed grains

Additional file 3: Table S1. Microfossil, Mg/Ca, δ18O, and δ13C data from the CbCS.

''AGG-RB-MJ-KW-RG-dataset'' contains the main dataset. The table is organized so that each row is a valley network entry. Columns include the valley name (if applicable), lat/long, network stream order, the fit parameters and their standard error, upper and lower confidence bounds, RMS, concavity index theta, and basin hydrology exponent c with upper and lower bounds. ''AGG-RB-MJ-KW-RG-Context'' contains the geological and geomorpohlogical context of each valley network. The table is organized so that each row is a valley network entry. Columns include the valley name (if applicable), lat/long, geological unit of incision, age of the terrain, Neukum timing of valley activity, concavity index and background concavity index (from Stepinski et al., 2004), and spatial relationships with other valleys.

Table S1. Zircon U-Pb dating results of clastic sedimentary rocks from the Huili Group. Table S2. Zircon Lu-Hf isotopic data of clastic sedimentary rocks from the Huili Group.

Additional file 1. Raw data including counts of all dinoflagellate cysts and other palynomorphs.

Summary of tropical cyclones that passed over Taiwan or close to it between 1982 and 2017. Also included are 1) a summary of precipitation and river discharge for 30 days around Super-Typhoon Haitang (2005) and Typhoon Morakot (2009); and, 2) wave data during the same 30-day windows.

Changes in vegetation have been observed in areas of the Arctic due to changing climate. This study examines a normalized difference vegetation index (NDVI) time series (2004–2018) of high spatial resolution satellite data (i.e., IKONOS, WorldView-2, WorldView-3) to determine if vegetation abundance has changed over the Cape Bounty Arctic Watershed Observatory, Melville Island, Nunavut. Image data were corrected to top-of-atmosphere reflectance and normalized for time series analysis using the pseudo-invariant feature (PIF) method. Percent vegetation cover measurements and indices derived from local climate data (growing degree days base 5 °C; GDD5) were used to contextualize NDVI trends in different vegetation types and within active layer detachments (ALDs). NDVI showed similar patterns within the different vegetation types and across the ALDs. There was no significant change in NDVI nor in GDD5 over time. However, there were statistically significant (p 5 and NDVI for all vegetation types. Using field measurements with high spatial resolution remote sensing data helps link changes in NDVI with changes to vegetation and earth surface processes. The challenges of integrating high spatial resolution satellite data from different sensors in a time series analysis are also discussed.
