Note:This Table displays all data sets of the LUQ LTER. It lists first the long-term data and then the completed ones. It is searcheable and sortable. Observe that:

It is sorted by duration (all long term data sets first) but it can be re-sorted by: Numeric Dataset ID, Data Set Identifier, and Duration by just clicking on the corresponding lable.
Each data set is classified as it was in Proposal 2006(LTER 4); the able that starts in page 67 and also a in Table 4 (page 67).
All long-term data sets have their collection dates (From-To).
On the top of this view, there are 5 different ways to search in this table including an open search and by the terms in the table 4 (see Long-Term Classification (Table 4 LUQ LTER 4 - page 19).
