| Variable name | ||||
| ID | 1 | 5 | Integer | System variable - Point identification number. |
| SLLONG | 6 | 13 | Real | Data variable - longitude of the tide- gauge station used in determining the sea-level trends. |
| SLLAT | 14 | 21 | Real | Data variable - latitude of the tide- gauge station used in determining the sea-level trends. |
| SLR | 22 | 29 | Real | Data variable - relative sea-level trend calculated from tide-gauge station measurements; values are expressed in mm/year. |
| SLG | 30 | 37 | Real | Data variable - long-term geologic trend. This variable is 0.0 for all stations with a relative sea-level trend value, and is included for compatibility within this series of NDPs. |
| SLC | 38 | 45 | Real | Data variable - corrected sea-level trend. Since the geologic trend variable contains values of 0.0, this variable appears identical to the relative sea-level trend variable; and is included only for compatibility within this series of NDPs. |
| SLS | 46 | 53 | Real | Data variable - local uplift or subsidence trend. Relative sea-level trend corrected for the global eustatic rate of sea-level rise (i.e., 1.5 mm/year). |
| SLYR | 54 | 57 | Integer | Data variable - years of record of the tide gauge station used in determining the sea-level trends. |

| SLNAME | 1 | 40 | Char | Data variable - name of the tide gauge used for determining the sea-level trends. |
| TRLONG | 41 | 48 | Real | Data variable - longitude of a tide-gauge station used for determining the tide range variables. |
| TRLAT | 49 | 56 | Real | Data variable - latitude of a tide-gauge station used for determining the tide range variables. |
| TRAVG | 57 | 64 | Real | Data variable - difference between mean high water and mean low water for 1992; values in meters. |
| TRMAX | 65 | 72 | Real | Data variable - maximum tide range, maximum measured range for the gauge station in 1992 (this value may be the "spring" or "diurnal" tide range, depending on geographic location); values in meters. |
| TRLVL | 73 | 80 | Real | Data variable - mean tide level, a plane midway between mean low water and mean high water in 1992. Values are reckoned from the West Coast Mean Low Water Datum. |

| TRID | 1 | 4 | Integer | Data variable - station number (used in the 1992 Tide Tables) of a tide-gauge station. |
| TRNAME | 5 | 54 | Char | Data variable - name of a tide-gauge station (from the 1992 Tide Tables). |
