The diver who is focused on small organisms or instruments at close range is likely to have diminished awareness of depth, buoyancy, current, surge, other divers, large organisms, and even the direction to the surface.<sup id="cite_ref-Haddock_and_Heine_6-1" class="reference"><a href="#cite_note-Haddock_and_Heine-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p><p>An accepted procedure for scientific blue-water collection diving with several working divers, is to tether the working divers to a central hub connected to a surface platform, and to have an in-water safety diver attend the hub. The tethers pass through fairleads at the hub and are tensioned by a weight at the end, which keeps slack out of the line and thereby reduces the risk of entanglement, and prevents the end of the line from passing through the fairlead. The tether serves to limit the distance a diver can move away from the hub, which is typically fastened to a substantial downline supported by a large buoy at the surface, and kept vertical by a weight. The float at the surface allows the divers to move freely in the water column within the constraint of the tether, and drift with the current. The tethers also allow rope signals between the safety diver and the working divers. The surface platform, generally a small boat, may be tethered to the buoy, and if there is sufficient wind to make this a problem a <a href="/wiki/Parachute_sea_anchor" class="mw-redirect" title="Parachute sea anchor">parachute sea anchor</a> can be deployed to minimise drift. Windage will generally position the buoy and boat downwind of the parachute. The other end of the tether is clipped to the diver's harness or buoyancy compensator by some form of quick-release shackle.<sup id="cite_ref-Haddock_and_Heine_6-2" class="reference"><a href="#cite_note-Haddock_and_Heine-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> These procedures and equipment can also be used at night. </p><p>If a sea anchor is deployed to limit drift, it must be kept clear of the divers to minimise the risk of entanglement, and it should be buoyed to prevent sinking in a calm. The sea anchor cable should be buoyant line for the same reason. Blue-water diving operations are constrained by water and weather conditions, including wind, sea state, current strength, visibility, and the presence of aggressive predators.<sup id="cite_ref-Haddock_and_Heine_6-3" class="reference"><a href="#cite_note-Haddock_and_Heine-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Black-water_diving">Black-water diving</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Open-water_diving&action=edit&section=4" title="Edit section: Black-water diving"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Black-water diving is mid-water diving at night, particularly on a moonless night.
