National Oceanographic Database (NODB) data series
Search
This interface allows you to build and then submit a search query for data series held in the NODB. The query is built from a number of categories, each of which is initially set to a broad default value that you can make narrower using the 'Refine' button.
It is not essential to start at the top of the form as the options available in all categories are automatically updated depending on your selections. We recommend that you start with your most important criteria. Your current search criteria are updated and displayed in the search form as you make your choices.
After each update, the number of data series that match your selection will be displayed at the bottom of the page. You will need to continue to refine your search until you have selected fewer than 1000 series, after which you will be able to view your results. You may, if you wish, refine any of your selections at any time. A history of your previous choices is maintained for each category.
A demonstration (best viewed with screen resolutions of 1024x768 or greater) is available for you to view.

Refine your search to specified dates and/or a time span greater or equal to a specified duration.
Use the "pull-down" menus (yyyy mm dd) to select data collected between specific dates. Your selection must be within the allowed range.
- If you select a start date and an end date then all records containing data collected between your start and end dates are returned.
To select a time span, for example longer than one month or two years, please enter a number in the duration box and use the "pull-down" menu to select its units. Your entry must be less than the maximum duration.
If used in conjunction with start and end date selections your search results will meet both criteria.

Restrict your search to a specified range of water depth (the distance between sea surface and sea bed not to be confused with the depth at which measurements were made). Enter a minimum and/or a maximum value. The minimum should be less than the maximum and only real numbers within the allowed range are accepted. Do not enter negative values.
- If you insert a minimum and maximum value then all records with a water depth between your minimum and maximum values are returned.
- If you insert a minimum value only then all records with a water depth equal to or more than your specified value are returned.
- If you insert a maximum value only then all records with a water depth less than or equal to your specified value are returned.
Not all records have a water depth value assigned. Should you wish to add these to your selection then click the include unknown box.

Restrict your search to measurements made within a specified range of depths. There are two ways to make a selection
1. Enter a minimum and/or a maximum depth value. Real numbers within the allowed range are accepted. The minimum should be less than the maximum. Positive values represent depths below and negative values heights above the sea surface.
- If you insert a minimum and maximum value then all records containing measurements at depths between your minimum and maximum values are returned.

2. Opt to select records which measured data either near to the sea surface or near to the sea bed. 'Near sea surface' is a fixed 10 m (i.e. depth range 0 to 10 metres) and 'near sea bed' is defined as within 5 m or 5% of the water depth, whichever is the smaller.
