Arabian Sea. m.v . British Esk "During the night a particularly strong and distinct patch of radar interference was noted by all observing officers. The sketch shows the phenomenon as seen on the 12-n .mile range of the 3-cm radar. The racon type mark varied in length from 1-3 n.miles at a nearest range of 5-10 n.miles. The effect was minimal on the 10-cm radar. "The bearing of the mark remained fairly constant at about 20 abaft the port beam or about 230 . Of particular ... was that around 1600 GMT to 1700 GMT (about 2 hours after sunset), when the mark on the radar was very distinct, the satellite communication system suffered a loss in signal strength sufficient to prevent transmission or reception, the bearing of the satellite being almost due south of the vessel. It was thought at the time that the signal mast had become aligned between the aerial and the satellite, but alteration of the ship's head to port or starboard did not cure the low signal strength. .. .. . "Of note, although this may have been a coincidence only, was that the vessel was passing through patches of bioluminescence at the time, mostly only bright enough to show up in the breaking waves of the ship's wake, but during the period ...

Red Sea. Aboard the m.v . Botany Bay . "At 1800 a crescent-shaped trace of spurious echoes appeared about 15 n. miles ahead of the vessel. This gradually developed, in an encirculating manner, until, by 1845 the echoes had totally surrounded the vessel. (See sketch.) The effect looked like, or could be likened to a plan view of a black island with sandy beaches around its perimeter. The echoes were significant with strong contrast and could even have been mistaken for land on the radar. The effect could not be removed or ... by changing range scales, motion modes, gain, tuning or perhaps most significantly, altering the pulse lengths. An identical effect was observed on the vessel's independent ARPA radar. The Master commented that although false echoes were invariably encountered in this region, he had not seen one such as this, which actually 'encapsulated' the vessel within the PPI of the radar. By 1935 the false echoes had dissipated into isolated batches splayed randomly across the screen." (Leslie, A.J .; "Radar Echoes," Marine Observer, 56:117, 1986.) Comment. In the Red Sea and Persian Gulf, similar false echoes are often associated with bioluminescent phenomenon. For details, see category GLW in our catalog: Lightning, Auroras.

The effect is sometimes quite dramatic. There are accounts of a 'low roar' as the bands of breaking waves, 'walls of white water,' pass a vessel. The bands are sometimes visible from aircraft, on ships' radar and are observed from satellites. In the Bay of Biscay 'boils' have been reported on the sea surface in the calm zones, and appear to be related to pulses of nutrients from the thermocline."

November 16, 1994. Eastern North Atlantic. Aboard the m.v . City of Durban . Enroute from Le Havre to Capetown. As seen by three of the ship's officers: "At 2230 UTC the observers noted on both the 3-cm and 10-cm radars, as well as visually, a wave or band-like phenomenon shown as a succession of 'bands' approximately 4 n.mile long with a uniform separation of about 0.8 n.mile. "The bands appeared ... if they were precipitation but on passing through one of them nothing was observed nor were there any other particles [i .e ., no wind-blown dust], seeing as the vessel was off the West African coast at the time. The bands themselves caused a rippling effect on the sea surface of roughly 150 m wide, giving an otherwise calm sea a black appearance beneath them on what was a well moonlit night. Although the phenomenon looked like rain bands, the observers could not give an otherwise definite solution for it."

... , just a mass of high-speed interacting bands of light. The effect is shown in the first sketch. As is usual on an 'all aft' ship, you become 'deaf' to the constant background noises, but I gradually became aware that the pulses of light seemed to match those of the main engine's throb, that is, about two per second. The radar (3 -cm radar, running on the 24 n. mile range), and the echo-sounder (indicating a water-depth of about 35 fathoms), were switched off in turn to see if any change was discernible, but there was not.

The Java Sea. "At 0210 LMT I witnessed the start of a bioluminescent display. My first impression was that the ship was being 'attacked' on all sides from different directions by pulsing light-bands. A dull 'strobe-light' effect flashed through a mist, giving the bands a dirty white to gray colouration which was not a 'smooth' colour, but rather grainy in appearance. The bands were about 2 m wide and about 2 m apart and moving at speed. At first it was difficult to discern whether or not the bands were in the water or just above the surface, as no form of reflection or ...

... 50-100 cm above the sea surface. The bands then changed into two rotating wheels; then a third wheel formed. All three rotated counterclockwise, with their hubs 300, 300, and 150 meters from the ship. The spokes stretched to the horizon. The display ceased for about 20 minutes and recommenced with four systems of onrushing parallel bands, which soon metamorphosed into four rotating wheels. Radar, visible light (from an Aldis lamp), and engine revolution appeared to have no effect on the spectacle. Next, evenly distributed, circular, flashing patches of brilliant blue-white light appeared all around the ship out to a distance of about 150 meters. This system of patches flashed away simultaneously the wheel display. The patches varied from 15-60 cm in diameter, and ... 114 times per minute. When an Aldis lamp played steadily on the patches, nothing happened. When the lamp was flashed, the whole array of flashing patches disappeared, only to reappear in about 2 minutes. Each patch seemed to consist of worm-like segments 2 cm long, 2 cm apart. The worms were all aligned perpendicular to a vector from the ship. In contrast to the bands and wheels, the worms were located about 5 cm below the surface of the water. Water samples revealed no luminous organisms -- only a few animals a few millimeters long. The sea was calm, visibility excellent, although atmospheric electrical activity could be seen all around. (Kuzmanov, Zoran; "Phosphorescence in the China Sea," Marine Observer, 53:85, 1983. ...

One can hypothesize that collective humanity recoiled at the TV images of the World Trade Center catastrophe. Improbable outputs of a distributed network of RNGs around September 11, 2001. But there are skeptical interpretations. For example, the sharp rise in global communications and radar activity might have somehow perturbed the RNGs.

Many have been the experiments in which humans attempt to affect the swinging of a pendulum, the throws of dice, or the output of a random-number generator. The parapsychologists declare that, YES, humans can exert tiny but statistically significant influences on such devices. But other scientists and the man-in-the-street would really like to see a robust physical effect, not just a bunch of statistics. An ambitious endeavor called the Global Consciousness Project just might be able to produce a more satisfying mind-over-matter effect. This Project is conducted by a group of scientists who maintain a dispersed network of random-number generators (RNGs).
