Buoys: There are two main classes of buoys: drifting and moored.
As the name implies, drifting buoys are not anchored to the seafloor. They are typically used to study currents and circulation patterns. A drogue (a cylindrical or funnel-shaped device) is sometimes added to have the surface buoy follow a subsurface current.
Subsurface drifting buoys , or floats , usually have variable buoyancy engines to descend to a predetermined depth where they follow this current and possibly collect environmental data.
The buoyancy engine is programmed to occasionally bring the float to the surface where it can telemeter its data back to shore. (A telemeter is an electrical apparatus for measuring a quantity—such as pressure, speed, or temperature—and transmitting the result especially by radio to a distant station.) Trajectories of individual floats show how the water moves horizontally, and trajectories of groups of floats show how the water is mixed by eddies. This information is important for understanding how water tracers and pollutants are transported by the ocean. The Advanced
Research and Global Observation Satellite (ARGOS) program is a large multinational effort to put thousands of floats in the world’s oceans.

Moored buoys are used for many purposes.
Some of the most common uses are:

Aids to Navigation (ATON)—used to mark hazards to mariners, harbor entrances and other navigable channels.
Data Collection Platforms —Mooredbuoys make excellent platforms for collecting data at one location anywhere in the ocean on time scales ranging from weeks to years. Sensors and instruments can be mounted anywhere from the seafloor on up to masts installed on the top of the mooring float
Marker Buoys —used to relocate objects on the seafloor
Ship Moorings —typically used to moor large commercial or military ships when dock space is not available or near-shore waters are too shallow. Also used for offshore
Other special types of buoys are:
Subsurface buoys  : used when surface measurements are not required. They also eliminate vandalism, which can be a big problem with surface buoys.
Self-deployed buoys have the anchor, line and sensors packaged in a compact assembly. Air deployed buoys are dropped from a plane.
Moored buoys come in a wide variety of shapes and sizes. Hull forms include disk, sphere, cone, boat hull and spar. The typical moored buoy consists of:
Tower for mounting antennas, sensors and solar panels
Float, usually has a well containing batteries
Bridle for attaching the mooring line
Mooring line to connect the bridle to the anchor

Moored buoys are important to the marine technologist because they make excellent platforms for collecting data anywhere in the ocean on time scales ranging from weeks to years. Sensors and instruments can be mounted anywhere from the seafloor on up to masts installed on the top of the mooring float. Anchors are connected to holding lines with acoustic couplings that are released to recall the instruments. Flotation holds the instruments and their tether line upright in the water column and brings them to the surface on release.
