“…Lagrangian simulations were performed for $950,000 particles, released from each vent site during the natural spawning period between January and March [53] and passively drifting with the threedimensional time-varying ocean velocities. To consider temporal fluctuations in current patterns, we modeled releases and dispersal between 1998 and 2007 assuming a typical PLD of 6 months [54] and a maximum PLD of 1 year [16].…”

“…The deployment and recovery of bottom cages enabled access to the seafloor throughout the year and the identification of seasonal reproduction patterns in vent species such as Bathymodiolus azoricus [66] and [67]. Nevertheless, this method is still limited to shallow, accessible vent environments and to large megafaunal species.…”

The responsiveness of benthic biological communities to climatic drivers and shifts makes them powerful indicators of biogeochemical and other environmental change in the oceans. In addition, benthic ecosystems have an economic value and are considered a vital marine resource. However deep-sea faunal dynamics and ecosystem functioning is not well defined. This has placed a higher priority in recent years on developing and sustaining long-term, time-series studies of benthic biodiversity, rate processes, and ecosystem change in deep-sea and extreme habitats. A few key long-term time-series sites exist across the global Ocean. Many of these sites are reviewed in this paper. However, much of the existing research is uncoordinated and the data collected are not integrated or standardized. This currently limits the use of these valuable datasets, which could be used for benthic modeling, global model validation and other societal benefits related to more effective and environmentally sustainable governance of human activities in the deep ocean. Furthermore, the time scales that can be studied within existing research frameworks are not currently sufficient to adequately address internationally-identified science priorities. These include assessing regional and global biodiversity, ecosystem functioning and the links between climate, terrestrial and marine ecosystems. In addition, the contribution of deep-sea ecosystems to global biogeochemical cycles and the potential alteration to ecosystem value and services due to anthropogenic activities is largely unknown. In order to maximize the societal benefit, biological time-series, in particular deep-sea sites, urgently require more coordination, integration, sustained funding and infrastructure. This is necessary to unify research methodologies, create synergies in the use of deep-sea technology, develop benthic models, and to stimulate more collaboration between programmes. National and international research organizations may provide a suitable framework within which further advances can be achieved. Only then will we better understand the goods and services provided by deep-sea ecosystems and the potential for environmentally sustainable exploitation of the deep ocean.

“…Reproductive periodicity appears variable in chemosynthetic mussels. In contrast with the seasonal reproduction reported for Bathymodiolus azoricus and B. childressi (Colaço et al 2006, Tyler et al 2006, B. thermophilus is reported to be aseasonal (Van Dover 2000). Lisin et al (1997) speculated that although C. kilmeri receives all or most of its nutrition from endosymbiotic bacteria, rich seasonal phytoplankton productivity off central California may contribute indirectly to the apparent seasonal repro- duction in C. kilmeri, by its possible influence on larval development and survival in the plankton.…”

“…Reports of reproduction in chemosynthetic bivalves include both seasonal and continuous spawning. Two mytilid species, Bathymodiolus azoricus (Colaço et al 2006) and B. childressi (Tyler et al 2006), have exhibited seasonal reproductive patterns. Vesicomyid bivalves are a common taxon at deep-sea vents and seeps, and have been reported to spawn continuously and seasonally.…”

Our knowledge of the reproductive biology and ecology of most deep-sea animals is very limited due to the logistic difficulties of deep-sea investigations. In this study, spawning by males and females of the vesicomyid bivalve Calyptogena soyoae and C. okutanii complex were observed in situ over 1 yr using the long-term deep-sea observatory located at cold seeps in Sagami Bay, Japan. Egg-and sperm-spawning events by clam aggregations occurred roughly 90 and 213 times m -2 for 1 yr, respectively, and the local population of the C. soyoae and C. okutanii complex yielded 5.8 × 10 8 eggs m -2 yr -1 into the water column over the seep location studied. Males displayed a 'sprinkle siphon' behavior, waving their siphons left and right to sprinkle sperm into the water. Female spawning by egg release into the water column was always preceded by male spawning and decreasing near-bottom current speeds. Two hypotheses are proposed for cues to stimulate egg release by C. soyoae/okutanii females. First, a 'double trigger' hypothesis requires the presence of sperm in the water column and decreasing current speed before eggs are released. Second, a 'single trigger' hypothesis requires that egg release is induced when compounds in or released with sperm exceed a threshold concentration. These results demonstrate the utility of long-term observatories for studies of deep-sea reproductive biology, particularly for species characterized by rare, episodic spawning events.
