Average Wave Period
Avg. Wave Period
The amount of time it takes for a wave to complete a full cycle from one peak to the following peak (in seconds). This average is calculated from the period of all waves during a designated time period.
Barometric Pressure
Baro. Pressure
Also referred to as atmospheric pressure, this is the pressure caused by the mass of air above the measuring point. Scientific units for this measurement are often given in millibars (mbar).
Bathymetry
The depth of a body of water, relative to sea level. It can also be thought of as the topography of the seafloor.
Chlorophyll
A green photosynthetic pigment found in the chloroplasts of phytoplankton. Measuring the concentration of chlorophyll is used as a proxy for biomass at the base of the marine food web.
Colored Dissolved Organic Matter (CDOM)
Colored DOM
Optically available dissolved organic matter in water. These organic molecules reduce the amount of light penetrating to depth and can therefore limit photosynthesis.
Dewpoint Temperature
Dew. Temp.
The temperature at which water vapor being held in the air will condense to form a liquid 'dew'. This temperature value is related to the amount of humidity in the air.
Dissolved Oxygen (DO)
The amount of gaseous oxygen in water or any other liquid. This is an important parameter for monitoring water quality as most marine organisms depend on oxygen for their survival.
Dominant Wave Period
Dom. Wave Per.
The period (in seconds) with the maximum wave energy over a certain time period.
Fluorescence
A portion of light absorbed by phytoplankton chlorophyll is re-emitted and measured as fluorescence. Chlorophyll fluorescence is used to quantify phytoplankton biomass.
Longwave Radiation
Energy emitted by the Earth, in the form of infrared rays. This occurs when the Earth heats up from the sun, re-emitting radiation into the atmosphere.
Omega Aragonite Saturation
Omega Arag. Sat.
A measurement of carbonate ion concentration; when the aragonite saturation value falls below 1, aragonite shells begin to dissolve. This is a variable commonly used in assessing ocean acidification.
Oxygen Concentration
Oxygen Conc.
A measure of the amount of dissolved oxygen (DO) in water given in units of milligrams oxygen per liter seawater (mg/L).
Oxygen Percent Saturation
Oxygen Pct. Sat.
A measure of the amount of dissolved oxygen (DO) in water given as the ratio of measured DO concentration relative to the DO concentration at saturation for water at that temperature and salinity, expressed as a percentage.
pH
The potential of hydrogen is a logarithmic scale used to measure the acidity or basicity of a solution dependent on the number of free hydrogen atoms in the solution. This scale ranges from 0 to 14, with higher acidity lowering the pH value. Typically, seawater has a pH around 8.
Relative Humidity
The ratio of water vapor in the air, relative to the amount of water vapor required for saturation at the same temperature.
Turbidity
A measurement of how far light can be transmitted through the water. Turbidity increases when suspended particles (organic material, sediment, etc.) are present in the water.
Wave Mean Direction
Wave Mean Dir.
The average direction from which the dominant wave period is coming. The units are in degrees from true North, increasing clockwise.
Wind Gust
A short burst of high speed winds, followed by a drop in wind speed.
Anomaly
Deviation from an average measurement over a certain time period. Observing anomalies is useful in comparing how current conditions differ from long-term averages of past measurements.
Climate
The description of the long-term pattern of weather in a particular region. There is an important distinction between weather and climate in that weather occurs over short time-scales (minutes to months), while climate refers to averages of weather over much longer time-scales.
Comparator
This feature allows users to compare the output of a variable from a specific computer model to observations at a location.
Forecast
A prediction of future conditions, made from a mathematical algorithm or model of the real world.
Hindcast
A way of testing a computer model in which known values are inputted into the model in order to test how well the output matches the known value.
Mean Lower Low Water (MLLW)
Average height of the lowest tide recorded daily over a time period.
