Description
Submarine canyons are major geomorphic features of continental margins around the world. Several recent multidisciplinary projects focused on the study of canyons have considerably increased our understanding of their ecological role, the goods and services they provide to human populations, and the impacts that human activities have on their overall ecological condition. Pressures from human activities include fishing, dumping of land-based mine tailings, and oil and gas extraction. Moreover, hydrodynamic processes of canyons enhance the down-canyon transport of litter. The effects of climate change may modify the intensity of currents. This potential hydrographic change is predicted to impact the structure and functioning of canyon communities as well as affect nutrient supply to the deep-ocean ecosystem. This review not only identifies the ecological status of canyons, and current and future issues for canyon conservation, but also highlights the need for a better understanding of anthropogenic impacts on canyon ecosystems and proposes other research required to inform management measures to protect canyon ecosystems.

الأخاديد البحرية هي السمات الجيومورفية الرئيسية للحواف القارية في جميع أنحاء العالم. أدت العديد من المشاريع الحديثة متعددة التخصصات التي ركزت على دراسة الأخاديد إلى زيادة فهمنا بشكل كبير لدورها البيئي، والسلع والخدمات التي تقدمها للسكان البشريين، وتأثيرات الأنشطة البشرية على حالتهم البيئية العامة. وتشمل الضغوط الناجمة عن الأنشطة البشرية صيد الأسماك، وإلقاء مخلفات المناجم البرية، واستخراج النفط والغاز. علاوة على ذلك، تعزز العمليات الهيدروديناميكية للوديان نقل القمامة إلى أسفل الوادي. قد تؤدي آثار تغير المناخ إلى تعديل شدة التيارات. من المتوقع أن يؤثر هذا التغيير الهيدروغرافي المحتمل على بنية وأداء مجتمعات الوادي بالإضافة إلى التأثير على إمدادات المغذيات إلى النظام البيئي في أعماق المحيطات. لا تحدد هذه المراجعة الحالة البيئية للأودية فحسب، والقضايا الحالية والمستقبلية للحفاظ على الأودية، بل تسلط الضوء أيضًا على الحاجة إلى فهم أفضل للتأثيرات البشرية المنشأ على النظم الإيكولوجية للأودية وتقترح أبحاثًا أخرى مطلوبة لإبلاغ تدابير الإدارة لحماية النظم الإيكولوجية للأودية.Translated Description (French)
Les canyons sous-marins sont des caractéristiques géomorphologiques majeures des marges continentales du monde entier. Plusieurs projets multidisciplinaires récents axés sur l'étude des canyons ont considérablement amélioré notre compréhension de leur rôle écologique, des biens et services qu'ils fournissent aux populations humaines et des impacts que les activités humaines ont sur leur état écologique global. Les pressions exercées par les activités humaines comprennent la pêche, le déversement de résidus miniers terrestres et l'extraction de pétrole et de gaz. De plus, les processus hydrodynamiques des canyons améliorent le transport en aval de la litière. Les effets du changement climatique peuvent modifier l'intensité des courants. Ce changement hydrographique potentiel devrait avoir un impact sur la structure et le fonctionnement des communautés de canyons ainsi que sur l'approvisionnement en nutriments de l'écosystème des grands fonds océaniques. Cette revue identifie non seulement l'état écologique des canyons et les problèmes actuels et futurs pour la conservation des canyons, mais souligne également la nécessité de mieux comprendre les impacts anthropiques sur les écosystèmes des canyons et propose d'autres recherches nécessaires pour éclairer les mesures de gestion visant à protéger les écosystèmes des canyons.Translated Description (Spanish)
Los cañones submarinos son las principales características geomorfológicas de los márgenes continentales de todo el mundo. Varios proyectos multidisciplinarios recientes centrados en el estudio de los cañones han aumentado considerablemente nuestra comprensión de su papel ecológico, los bienes y servicios que proporcionan a las poblaciones humanas y los impactos que las actividades humanas tienen en su condición ecológica general. Las presiones de las actividades humanas incluyen la pesca, el vertido de relaves de minas terrestres y la extracción de petróleo y gas. Además, los procesos hidrodinámicos de los cañones mejoran el transporte de basura hacia abajo del cañón. Los efectos del cambio climático pueden modificar la intensidad de las corrientes. Se predice que este posible cambio hidrográfico afectará la estructura y el funcionamiento de las comunidades de los cañones, así como el suministro de nutrientes al ecosistema de las profundidades oceánicas. Esta revisión no solo identifica el estado ecológico de los cañones y los problemas actuales y futuros para la conservación de los cañones, sino que también destaca la necesidad de una mejor comprensión de los impactos antropogénicos en los ecosistemas de los cañones y propone otras investigaciones necesarias para informar las medidas de gestión para proteger los ecosistemas de los cañones.Files
