The mosaic of sonographs which was produced shows two sets of mainly linear targets. These targets can be related to locally steep scarps on the sea-floor and ate interpreted as the scarps of steep faults. The fault scarps comprising the larger set are tens of kilometres long and subparallel to the median valley but tend to be curved in plan near fracture zones. The most satisfactory explanation for these is that they are formed by caldera-collapse over an elongate cigar-shaped magma chamber which lies beneath the inner floor of the median valley. The fault scarps of the other set occur only in fracture zone valleys and run obliquely to the general trend of the transform fault zone. They appear to be subsidiary strike-slip and normal faults generated within the zone of shear which characterizes a transform fault. Our results indicate that the upper crust of a slow-spreading ridge is faulted into long narrow parallel-sided slices within the inner floor, probably by the faults which produce the inner walls of the median valley.</p></div>","PeriodicalId":11253,"journal":{"name":"Deep Sea Research and Oceanographic Abstracts","volume":"23 11","pages":"Pages 1005-1023, IN1-IN10"},"PeriodicalIF":0.0,"publicationDate":"1976-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0011-7471(76)90877-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74213107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a mid-ocean profile of the upper 400 m, there emerge: (1) a zone including subarctic near-surface waters and extending southward at greater depths, (2) a narrow zone to the south concentrated above the first zone, and (3) a zone yet farther south ranging from the surface to a lower boundary that shoals northward. These zones correspond generally to the following respective hydrographic features: (1) the Subarctic Water Mass and the Intermediate Water, centered on a salinity minimum, (2) an unnamed mid-latitude zone characterized by a salinity maximum above the salinity minimum and (3) the warm, high salinity, Central Water Mass. Toward the North American continent, distributions of species from the two more northern (and deeper) zones overlap as the respective water masses become mixed in the California Current. The southernmost (and shallowest) zone retains hydrographic and biologic continuity as a surface layer at the outer edge of the California Current.
