pulses of upwelling in the benguela system regularly have a duration of 10 days, an optimal period for biological production. it is estimated that the annual new production in the benguela system is 4.7 × 10^13 gc/y, making the benguela system 30 to 65 times more productive per unit area than the global ocean average.
a multibeam echosounder is a type of sonar that is used to map the seabed. like other sonar systems, multibeam systems emit sound waves in a fan shape beneath a ship's hull. the amount of time it takes for the sound waves to bounce off the seabed and return to a receiver is used to determine water depth.
an organ system is a group of organs that work together as a biological system to perform one or more functions. each organ does a particular job in the body, and is made up of distinct tissues . organs systems and their functions. there are eleven distinct organ systems in human beings, which form the basis of anatomy. other animals have .
sosus systems consisted of bottom-mounted hydrophone arrays connected by underwater cables to facilities ashore. the individual arrays were installed primarily on continental slopes and seamounts at the axis of the deep sound channel and normal to the direction in which they were to cover. the combination of location within the ocean and the .
a liner conference system also called a 'shipping conference' is an agreement within the shipping industry in relation to ocean liners. typically, the agreement is between two or more shipping companies to provide scheduled cargo and/or passenger service on a particular trade route under uniform rates and common terms.
an ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. ocean currents are primarily horizontal water .
sea skimming is a technique many anti-ship missiles and some fighter or strike aircraft use to avoid radar, infrared detection, and to lower probability of being shot down during their approach to the target. 3 disadvantages. 4 possible defenses. 4.1 phalanx ciws. 5 use in major wars. sea-skimming anti-ship missiles try to fly as low as is .
ship management information system is based on the management philosophy which states that 'skill management is the basic, security control is the core and the success control is the purpose'. in order to satisfy the requirement of classification and to satisfy multiple ship equipment maintenance system and ship inspection management system, there is ship machinery planned maintenance system .
logistics automation is the application of computer software or automated machinery to improve the efficiency of logistics operations. typically this refers to operations within a warehouse or distribution center, with broader tasks undertaken by supply chain engineering systems and enterprise resource planning systems.. logistics automation systems can powerfully complement the facilities .
an ocean data acquisition system odas is a set of instruments deployed at sea to collect as much meteorological and oceanographic data as possible. with their sensors, these systems deliver data both on the state of the ocean itself and the surrounding lower atmosphere.
to remove as much cargo as possible, a conveyor belt system was used. when the weather and tide permitted, workers on the wreck filled jumbo-sized bags with the ship's cargo. those bags were then brought up the cliff by the conveyor, which had been placed on the cliff just above the wreck. the operation ended on 29 may 2003. although most of the cargo was removed, some was lost to the ocean.
