Recorded bottom-water temperature excursions of several degrees in some areas such as the Bush Hill site (4–5 °C at 500-m (1,640-ft) depth) are believed to result in dissociation of hydrates, resulting in an increase in gas fluxes (MacDonald et al., 1994). Although not as destructive as the <a href="/wiki/Volcanism" title="Volcanism">volcanism</a> at vent sites of the <a href="/wiki/Mid-ocean_ridge" title="Mid-ocean ridge">mid-ocean ridges</a>, the dynamics of shallow hydrate formation and movement will clearly affect <a href="/wiki/Sessility_(motility)" title="Sessility (motility)">sessile animals</a> that form part of the seepage barrier. There is potential of a catastrophic event where an entire layer of shallow hydrate could break free of the bottom and considerably affect local communities of chemosynthetic fauna.<sup id="cite_ref-MMS_2006_21-28" class="reference"><a href="#cite_note-MMS_2006-21"><span class="cite-bracket">[</span>21<span class="cite-bracket">]</span></a></sup> At deeper depths (>1,000 m, >3,281 ft), the bottom-water temperature is colder (by approximately 3 °C) and undergoes less fluctuation. The formation of more stable and probably-deeper hydrates influences the flux of light hydrocarbon gases to the sediment surface, thus influencing the surface morphology and characteristics of chemosynthetic communities. Within complex communities such as Bush Hill, <a href="/wiki/Petroleum" title="Petroleum">petroleum</a> seems less important than previously thought (MacDonald, 1998b).<sup id="cite_ref-MMS_2006_21-29" class="reference"><a href="#cite_note-MMS_2006-21"><span class="cite-bracket">[</span>21<span class="cite-bracket">]</span></a></sup> </p><p>Through <a href="/wiki/Taphonomy" title="Taphonomy">taphonomic</a> studies (death assemblages of shells) and interpretation of seep assemblage composition from cores, Powell et al.

Adult mussel growth rates were similar to mussels from a littoral environment at similar temperatures. Fisher also found that juvenile mussels at hydrocarbon seeps initially grow rapidly, but the growth rate drops markedly in adults; they grow to reproductive size very quickly. Both individuals and communities appear to be very long-lived. These <a href="/wiki/Methane" title="Methane">methane</a>-dependent mussels have strict chemical requirements that tie them to areas of the most active seepage in the Gulf of Mexico. As a result of their rapid growth rates, mussel recolonization of a disturbed seep site could occur relatively rapidly. There is some evidence that mussels also have some requirement of a hard substrate and could increase in numbers if suitable substrate is increased on the seafloor (Fisher, 1995). Two associated species are always found associated with mussel beds—the gastropod <i><a href="/wiki/Bathynerita_naticoidea" class="mw-redirect" title="Bathynerita naticoidea">Bathynerita naticoidea</a></i> and a small <a href="/wiki/Alvinocarididae" title="Alvinocarididae">Alvinocarid</a> shrimp—suggesting these endemic species have excellent <a href="/wiki/Biological_dispersal" title="Biological dispersal">dispersal abilities</a> and can tolerate a wide range of conditions (MacDonald, 2002).<sup id="cite_ref-MMS_2006_21-38" class="reference"><a href="#cite_note-MMS_2006-21"><span class="cite-bracket">[</span>21<span class="cite-bracket">]</span></a></sup> </p><p>Unlike mussel beds, chemosynthetic clam beds may persist as a visual surface phenomenon for an extended period without input of new living individuals because of low dissolution rates and low sedimentation rates. Most clam beds investigated by Powell (1995) were inactive. Living individuals were rarely encountered. Powell reported that over a 50-year timespan, local extinctions and recolonization should be gradual and exceedingly rare. Contrasting these inactive beds, the first community discovered in the Central Gulf of Mexico consisted of numerous actively-plowing clams. The images obtained of this community were used to develop length/frequency and live/dead ratios as well as spatial patterns (Rosman et al., 1987a).<sup id="cite_ref-MMS_2006_21-39" class="reference"><a href="#cite_note-MMS_2006-21"><span class="cite-bracket">[</span>21<span class="cite-bracket">]</span></a></sup> </p><p>Extensive <a href="/wiki/Bacterial_mat" class="mw-redirect" title="Bacterial mat">bacterial mats</a> of free-living <a href="/wiki/Bacteria" title="Bacteria">bacteria</a> are also evident at all hydrocarbon seep sites.

Carney (1993) first reported a potential imbalance that could occur as a result of chronic disruption. Because of sporadic recruitment patterns, predators could gain an advantage, resulting in exterminations in local populations of mussel beds. It is clear that seep systems do interact with the background fauna, but conflicting evidence remains as to what degree outright predation on some specific community components such as tubeworms occurs (MacDonald, 2002). The more surprising results from this recent work is why background species do not utilize seep production more than seems to be evident. In fact, seep-associated consumers such as <a href="/wiki/Galatheid" class="mw-redirect" title="Galatheid">galatheid</a> crabs and <a href="/wiki/Neritidae" title="Neritidae">nerite</a> gastropods had isotopic signatures, indicating that their diets were a mixture of seep and background production.

tubeworm communities continues to improve; however, chemosynthetic communities cannot be reliably detected directly using <a href="/wiki/Geophysical_survey" title="Geophysical survey">geophysical techniques</a>. Hydrocarbon seeps that allow chemosynthetic communities (<a href="/wiki/Guaymas_Basin" title="Guaymas Basin">Guaymas Basin</a>) to exist do modify the geological characteristics in ways that can be remotely detected, but the time scales of co-occurring active seepage and the presence of living communities is always uncertain. These known sediment modifications include (1) precipitation of <a href="/wiki/Authigenic" class="mw-redirect" title="Authigenic">authigenic</a> carbonate in the form of micronodules, <a href="/wiki/Nodule_(geology)" title="Nodule (geology)">nodules</a>, or rock masses; (2) formation of <a href="/wiki/Gas_hydrate" class="mw-redirect" title="Gas hydrate">gas hydrates</a>; (3) modification of <a href="/wiki/Sediment" title="Sediment">sediment</a> composition through concentration of hard chemosynthetic organism remains (such as shell fragments and layers); (4) formation of interstitial gas bubbles or hydrocarbons; and (5) formation of depressions or pockmarks by gas expulsion. These features give rise to acoustic effects such as wipeout zones (no echoes), hard bottoms (strongly reflective echoes), bright spots (reflection enhanced layers), or reverberant layers (Behrens, 1988; Roberts and Neurauter, 1990). Potential locations for most types of communities can be determined by careful interpretation of these various geophysical modifications, but to date, the process remains imperfect and confirmation of living communities requires direct visual techniques.<sup id="cite_ref-MMS_2006_21-42" class="reference"><a href="#cite_note-MMS_2006-21"><span class="cite-bracket">[</span>21<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Fossilized_records">Fossilized records</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Cold_seep&action=edit&section=22" title="Edit section: Fossilized records"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:CretaceousSeep17.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/e/ea/CretaceousSeep17.jpg/220px-CretaceousSeep17.jpg" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/e/ea/CretaceousSeep17.jpg/330px-CretaceousSeep17.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/e/ea/CretaceousSeep17.jpg/440px-CretaceousSeep17.jpg 2x" data-file-width="1200" data-file-height="900" /></a><figcaption>Late <a href="/wiki/Cretaceous" title="Cretaceous">Cretaceous</a> cold seep deposit in the <a href="/wiki/Pierre_Shale" title="Pierre Shale">Pierre Shale</a>, southwest South Dakota</figcaption></figure> <p>Cold seep deposits are found throughout the <a href="/wiki/Phanerozoic" title="Phanerozoic">Phanerozoic</a> geologic record, especially in the Late <a href="/wiki/Mesozoic" title="Mesozoic">Mesozoic</a> and <a href="/wiki/Cenozoic" title="Cenozoic">Cenozoic</a>.
