Earth's mean temperature has been steadily increasing for many decades due to increasing concentrations of greenhouse gasses, such as carbon dioxide, in the atmosphere. Most of the heat trapped within the atmosphere in the past has been stored in the oceans throughout the world. As a result, the steadily increasing oceanic heat energy supply results in the formation and building of storms as they pass over these increasingly warming waters. This has and will result in increasing numbers of devastating cyclonic storms being formed in the tropical oceanic regions. Additionally, this warming has also increased the intensity of cyclonic ocean storms causing ever increasing destruction of onshore property and human suffering and death when these storms make landfall. In the United States alone, the cost of hurricane landfalls totals billions of dollars and many lives are lost each year.
Additionally, it is scientifically well established that coastal upwelling of deep oceanic water is responsible for much of the marine biome productivity of coastal areas. As oceanic currents approach, nutrient rich waters are pushed up onto the continental shelves. As these waters are mixed with surface waters, marine biome productivity improves. This increase in productivity from upwelling is also true of oceanic areas where deep water currents encounter underwater seamounts and bring cool, nutrient rich water up to the photic zone where sunlight can foster growth of photosynthetic biome. The warming of the earth's climate has thickened the warm upper layer of the oceans and reduced the natural effectivity of onshore upwelling of nutrient rich waters. Thus, there is a clear need for marine mobile systems that can enrich and/or cool selected oceanic regions by artificial upwelling.

DETAILED DESCRIPTION OF EMBODIMENTS
Oceanic water upwelling devices have been conceived to enrich or cool surface or near-surface waters. These devices, however, have been either floating wherever the winds or currents take them or anchored in a single location. The embodiments of this invention transport the upwelling devices wherever they are most needed at the time they are most needed and utilize the traveling velocity or propulsion to upwell the deep water to the surface or near-surface waters. Thus, these embodiments demonstrate a clear advantage over previously conceived devices.
FIG. 1 illustrates a mobile upwelling device 1 being towed by a surface marine vessel 2 such as a tugboat on an ocean surface 3. The upwelling device is comprised of a weighted, funneling dive plane 4 connected to a water transport tube 5. The funneling dive plane 4 is connected to the surface marine vessel 2 by a tow line 6. The funneling dive plane 4 is also connected to a water transport tube 5 the outlet end of which is connected by a float connecting line 7 to a buoyant float 8 which keeps the water transport tube 5 outlet in or near surface waters. As the mobile upwelling device 1 is propelled forward by the surface marine vessel 2, the dive plane 4 descends deep into the ocean due to the dive angle of the funneling dive plane 4 and the water that is forced onto the weighted dive plane is propelled the water up and through the water transport tube 5 where the upwelled water is ejected into the surface or near-surface waters near the float 8 to be mixed with the near-surface waters. This mixing facilitates the use of the cool, nutrient rich deep water by marine plants and animals thereby improving the health of the oceans. Additionally, if located in the pathway of cyclonic storms, this upwelling can alter the pathway of and reduce the intensity of the storms and reduced onshore damage by cooling the surface and near-surface waters. The depth of the water, and therefore the temperature and nutrient content of the upwelled water, can be adjusted by adjustment of the length of the tow line 6 and by altering the angle of the funneling dive plane 4. For example, if the dive angle is increased, the depth from which upwelled water is brought to the surface or near-surface will be deeper. If that dive angle is decreased, this depth will be shallower.
FIG. 2 illustrates, in more detail, a mobile marine upwelling device comprised of a funneling dive plane 4, including a weight 9 on the forward end of the dive plane 4 which ensures that the forward motion pushes the plane deep into the water by tipping the plane down at the forward end. A tow line 6 is connected to the dive plane 4 aft of the weight 9 and forward of the water transport tube 5 on each side of the dive plane 4 such that the plane angle is down toward deeper waters. The angle of the dive plane 4 may be altered to dive deeper while in motion by adjusting the length of the dive angle adjustment line 10. The outlet end of the water transport tube 5 is connected to the float 8 by the float connecting line 7.
FIG. 3 illustrates a water upwelling system 1 propelled forward by a tow line 6 connected to a submersible marine vessel 11. The depth of the water upwelled toward the ocean surface 3 by this system is determined by the dive depth of the submersible vessel 11 below the ocean surface 3 and the overall length of the upwelling device 1. As such, the weight 9 on the dive plane 4 may be small or eliminated. As the submersible vessel 11 travels forward pulling the dive plane 4, the water transport tube 5, the float connecting line 7, and the float 8, cool, nutrient rich water is transported up the water transport tube 5 toward the float 8 until it exits and mixes with the surface or near-surface water.
FIG. 4 illustrates how one or more towed upwelling systems (not shown may be deployed along the coastal waters of a country or continent to enrich or cool the adjacent coastal shelf waters. The North American west coast 12 is illustrated along with a representative vessel path 13 that an upwelling vessel or fleet of vessels (not illustrated) may take. This system may be deployed in deep water very near the edge of the continental shelf to bring up nutrient rich water from 100 meters depth or more so the nearby coastal marine biome will benefit from this enrichment. In some cases, the upwelled water may still be lacking in ideal nutrients. In such a case, nutrients, such as iron, may be dispersed by the vessel along the route in areas where such nutrients are needed.
FIGS. 5 and 6 illustrate how one or more mobile upwelling devices (not shown) could travel in front of, or in the likely path of, a cyclonic storm cooling the surface and near-surface water to reduce the intensity of the storm or, perhaps, to redirect the storm away from vulnerable onshore populations. FIG. 5 illustrates the storm path 14 an oceanic cyclonic storm 15 would likely take along the northeast coast of South America 16, through Caribbean islands 17, and pummeling part of the east coast of North America 18 potentially causing much human and property damage. FIG. 6 illustrates a potential route 19 that one or more mobile upwelling vessels could take that could reduce the damage from the cyclonic storm 15 and the potential resultant path 20 of cyclonic storm 15, which would be deflected away from vulnerable shores.
FIGS. 7 and 8 also illustrate how a mobile upwelling device may provide needed benefit. FIG. 7 illustrates the approximate cyclonic storm path 21 of hurricane Iniki 24 which, in 1992, devastated the island of Kauai 22 in the Hawaiian archipelago 23 causing over 3 billion dollars in damage.
FIG. 8 illustrates how creating a cool water barrier by upwelling cool water along a route 25 could have potentially altered the path 26 of a cyclonic storm 24, such as Iniki, that it could completely miss the Hawaiian Island archipelago 23.
FIG. 9 illustrates a semi-autonomous upwelling system. The system includes communications 27 (shown as dashed lines) between antennae 28 on the float 8, a surface marine vessel 2 and communication satellites 29 and GPS satellites 30 as well as between the float 8 and the surface marine vessel 2 such that a remote operator (not illustrated) can alter the course, or speed of the upwelling system as needed. In this instance, the towing vessel 2 can communicate with both the GPS satellites 29 and, the communication satellites 30 to determine the position and course of the cyclonic storm, the position and course of the upwelling system, and if needed, relays course and speed commands from a remote, onshore controller (not illustrated). The float 8 also can have communication with the water transport tube 5 which can transmit upwelling data from sensors (not shown) within the water transport tube 5 such as upwelled water temperature, flow rate, and water chemical composition back to the controller (not shown) or to the surface marine vessel 2. When deployed near severe storms, the amount of buoyancy of the float 8 may be altered to protect it from storm damage.
FIG. 10 illustrates a semi-autonomous upwelling system, wherein the towing vessel is a fully submersible marine vessel 11. In this case, since the submersible marine vessel 11 cannot communicate directly with satellites because it is not on the surface. Communication satellite(s) 30 and GPS satellite(s) 29 use communications 27 (shown in dashed lines) by way of antenna 28 which relays to a bidirectional underwater communication system 31 on the float 8 directly which, in turn relays course correction information to the submersible marine vessel 11. Thus, a remote onshore controller can monitor and guide the upwelling system. Clearly such semi-autonomous systems could be converted to fully autonomous if proven reliable and effective enough. Because of the risk to vessel operators involved in deployment in the vicinity of potentially fatal storm systems, a semi-autonomous or fully autonomous system could be the system of choice for such storm abatement.
FIG. 11 illustrates a surface upwelling vessel 36 in which gravitational forces propel the water from the water transport tube input end 32 through the water transport tube 5 to the surface upwelling vessel 36. Once the upwelled water reaches the vessel hull, water is thrust out through the propulsion tubes 33 in the stern of the vessel below the water line 3.
FIG. 12 illustrates, in a more detailed cross-section view of the aft portion of the vessel through the starboard propulsion tube 33 shown in FIG. 11, showing how the upwelled water is used to propel the vessel forward by motors 34 which turn the drive shafts 38 and the propellers 37 within the propulsion tubes 33. The upwelled nutrient rich, cool water is brought into the propulsion water storage chamber 35 by gravitational forces since this chamber is below the vessel water line 3 and conducted into the propulsion water storage chamber by the water transport tube 5 and then forced out through the propulsion tubes 33 by the propellers at a high flow rate. Thus, the upwelled water propels the vessel on the desired route as well as mixes the upwelled water with the surrounding surface waters due the turbulence caused by the thrust.
FIG. 13 illustrates a mobile upwelling vessel 36 wherein the upwelling water transport tube can be pivoted or rotated to upwell from a desired depth. This embodiment also provides a telescoping mechanism for the upwelling tube to enable reaching deeper waters. In this illustration, the upwelling tube is in a position wherein the upwelling tube has not been rotated or telescoped and the propulsion water is acquired from the water transport input end 32 located near the ocean surface. The output from the propulsion tubes 33 is located just aft of the water transport input end 32. The propulsion water travels forward through the upwelling transport tube, into the propulsion water storage chamber, out through the propulsion tubes, and past the rudders 39 thereby propelling the vessel forward.
FIG. 14 illustrates the mobile upwelling vessel of FIG. 13 wherein the upwelling water transport tube 5 has been rotated about the pivot port 41 such that the water transport tube input end 32 is located at a desired depth 42. The cool, nutrient rich, water is transported by the force of gravity through the water transport tube input end 32 of the telescoping tube 40, through the pivoting water transport tube 5, through the pivot port 41 and into the propulsion water storage chamber 35. This propulsion water storage chamber 35 brings the water aft to the propulsion tubes (not shown) where the propellers 37 force water out propelling the vessel forward. Steering of the forward motion of the vessel 1 is accomplished by rotation of the rudders 39.
FIG. 15 further illustrates the upwelling propulsion system shown in FIG. 14. In this case, electric motors are used to provide the torque need for propulsion and upwelling. Fuel such as compressed hydrogen, stored in the fuel storage chamber 48 is conducted to the generators 46 through fuel lines 47. These generators 46 provide electric power through power cables 45 to electric motors 44. The torque output of the electric motors 44 is coupled to the propellers 33 by articulated drive shafts 43 turning the propellers 37 forcing the water from the propulsion water storage chamber 35 out through the propulsion tubes 33. Vessel steering is accomplished by rudders 39. Other sources of the required torque could be used.
