This paper presents the results of an ongoing effort to create a unique resource at the Center for Ocean Ventures and Entrepreneurship (COVE) in Halifax Nova Scotia. COVE is a collaborative facility for applied innovation in the ocean sector. Its mission is to propel the ocean economy by providing high quality marine infrastructure and a collaborative space in which a community of ocean enterprises can start, grow and prosper. The primary goal is to support ocean technology commercialization. COVE is a community that brings together the best and the brightest to push ocean tech advances to market. The facility includes a mix of short and long-term workspace to support members locally and those visiting from other locations. There is also a full mix of programming that can be accessed on site and on a virtual basis. The amenities available to tenants of COVE include electronics fabrication and testing facilities, mechanical fabrication space, office space, storage spaces, waterside marine services and shared services such and a large multipurpose room for training and events. This paper discusses two key themes. First it reviews how COVE's unique facility and infrastructure has inspired ocean technology developments. In addition to results to date, this paper discusses the design of a coastal ocean observing system planned for COVE. This system will be distinctive in that it is intended to support technology commercialization, not scientific research. The design of this observatory includes a series of cabled nodes and options for various buoy-based surface expressions.

Acetylene has been pyrolysed in a flow reactor system at 914–1039 K and 6–47 kPa, with residence times between 3 and 50 ms. Pressures at the reactor inlet were greater than those at the outlet because of viscous drag. This permitted calculation of the viscosity of acetylene, which was found to have a dependence on the absolute temperature proportional to T 0.71±0.08 . Expressions were developed to describe the yields of products in a compressible gas undergoing simultaneous viscous expansion and slow reaction. Yields of products were measured by gas chromatography. Vinylacetylene and benzene were found to be primary products, with orders of two and three, and activation energies of 208±13 and 164±17 kJ mol −1 , respectively. Acetone, which occurs as an impurity in commercial acetylene, was found to accelerate the formation of both products by a factor between two and four. This provided evidence to support a free-radical mechanism with a second-order initiation step, whose activation energy is approximately in the range from 220 to 250 kJ mol −1 . The chain length was estimated to be between 10 and 150, depending on the conditions and the identity of the termination step.
