Foliar Ca, Sr and 87Sr/86Sr measurements on Watershed 1 at the Hubbard Brook Experimental Forest, 1999 - present

This dataset includes ICP-OES analyses of Ca and Sr concentration and thermal ionization mass spectrometry analyses of 87Sr/86Sr ratios for annual samples of Watershed 1 understory foliage. Additional foliar elements were analysed and are included in the data table. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.
