Full Citation Examples
NOAA has designed and is currently implementing a hyporheic monitoring plan for the Thornton Creek watershed in North Seattle. This work is being conducted for Seattle Public Utilities, who in 2015 completed two large-scale floodplain reconnection projects in the Thornton Creek Watershed. This study will evaluate restoration effectiveness by comparing control and treatment study reaches to each other and to forested references streams before and after restoration. NOAAs data collection focuses on hyporheic invertebrates, water temperature, and nutrient concentrations.
Hyporheic and surface water concentrations of DOC, TN, TP, and dissolved nutrients.

|---|---|
| Approximate Percentage of Budget for these Data Devoted to Data Management: | 10% |
| Do these Data Comply with the Data Access Directive?: | No |
| Is Access to the Data Limited Based on an Approved Waiver?: | No |
| If Distributor (Data Hosting Service) is Needed, Please Indicate: | No |
| Approximate Delay Between Data Collection and Dissemination: | 240 days |
| If Delay is Longer than Latency of Automated Processing, Indicate Under What Authority Data Access is Delayed: |
Project was funded by non-federal agency. Unclear at what point they will choose to make data publicly available. |
| Actual or Planned Long-Term Data Archive Location: | NCEI-MD |
| Approximate Delay Between Data Collection and Archiving: | 240 days |
| How Will the Data Be Protected from Accidental or Malicious Modification or Deletion Prior to Receipt by the Archive?: |
The Northwest Fisheries Science Center facilitates backup and recovery of all data and IT components which are managed by IT Operations through the capture of static (point-in-time) backup data to physical media. Once data is captured to physical media (every 1-3 days), a duplicate is made and routinely (weekly) transported to an offsite archive facility where it is maintained throughout the data's applicable life-cycle. |
