The role of eddies and topography in the export of shelf waters from the West Antarctic Peninsula shelf

first_imgOceanic heat strongly influences the glaciers and ice shelves along West Antarctica. Prior studies show that the subsurface onshore heat flux from the Southern Ocean on the shelf occurs through deep, glacially carved channels. The mechanisms enabling the export of colder shelf waters to the open ocean, however, have not been determined. Here, we use ocean glider measurements collected near the mouth of Marguerite Trough (MT), west Antarctic Peninsula, to reveal shelf‐modified cold waters on the slope over a deep (2,700 m) offshore topographic bank. The shelf hydrographic sections show subsurface cold features (θ <=1.5 °C), and associated potential vorticity fields suggest a significant instability‐driven eddy field. Output from a high‐resolution numerical model reveals offshore export modulated by small (6 km), cold‐cored, cyclonic eddies preferentially generated along the slope and at the mouth of MT. While baroclinic and barotropic instabilities appear active in the surrounding open ocean, the former is suppressed along the steep shelf slopes, while the latter appears enhanced. Altimetry and model output reveal the mean slope flow splitting to form an offshore branch over the bank, which eventually forms a large (116 km wide) persistent lee eddy, and an onshore branch in MT. The offshore flow forms a pathway for the small cold‐cored eddies to move offshore, where they contribute significantly to cooling over the bank, including the large lee eddy. These results suggest eddy fluxes, and topographically modulated flows are key mechanisms for shelf water export along this shelf, just as they are for the shoreward warm water transport.last_img read more

Wave & tidal energy market could reach $3.9 billion by 2025, report says

first_imgGlobal wave and tidal energy market is expected to grow at a CAGR of 42.5% and reach $3.9 billion by 2025, according to a report published by Grand View Research, Inc. Ocean energy is witnessing significant development in terms of new projects in various economies including the UK, Ireland, Sweden, Portugal, Thailand, India, Japan, China, Canada, and U.S., which is likely to fuel market growth over the coming years, the report states. On the other hand, high cost and socio-economic and environmental barriers are likely to restrain the development of the market over the 2018-2025 period.Nevertheless, the report expects the projected growth to be fuelled by the need to reduce dependency on fossil fuels, increasing investments, and supportive government regulations.Asia Pacific is expected to be a lucrative market for the technology due to government initiatives, the report states.The number of companies in the global wave and tidal energy market has increased in recent years, and these companies are constantly making significant efforts to advance their technologies and deploy novel and improved equipment, the report points out. R&D, new project developments, partnerships, and acquisitions are some of the major strategies being adopted by the companies in the industry.Wave energy is likely to register significant growth in the coming years based on extensive R&D and new project developments in numerous economies including Ireland, Sweden, Portugal, U.S., China, and New Zealand, according to the report. The tidal segment, which dominated the market on the account of high technological know-how, could see its growth somewhat hindered by environmental concerns related to the technology.last_img read more

IPPO gives food packs to 5,000 poor families

first_imgHethanked local government units for their cooperation. “Thebayanihan system is really a big helpto the affected families. Kung may maiponpa tayo until April 30, we will sustain our program para walang magugutom. Kung may nais na tumulong willing naman kami mag-facilitate,”Lucas added./PN TheIPPO selected the poorest barangays in every town – with the help of municipalsocial welfare and development (MSWD) offices – for the civic outreach.  Eachfood pack contained rice, canned goods, sugar, coffee, noodles, and vegetables. Prioritybeneficiaries in the distribution conducted on April 15 were the poorestfamilies, said Police Colonel Paul Kenneth Lucas, IPPO director. Theenhanced community quarantine will end on April 30.center_img “Wehope this humble support can help ease the burden of poor families who are themost badly affected by the enhanced community quarantine,” saidLucas.
