The underlying logic is sound: as sea ice melts, it exposes darker ocean water, which absorbs more of the sun's heat, causing the water temperatures to increase.

The Arctic is warming more than twice as fast as the rest of the planet, because as ice melts at the top of the world, there is less of it to reflect sunlight back into space, so more of it is absorbed by ocean waters; more absorbed sunlight means even warmer temperatures, which means more ice melt a circular process known as Arctic amplification.

The CDR potential and possible environmental side effects are estimated for various COA deployment scenarios, assuming olivine as the alkalinity source in ice ‐ free coastal waters (about 8.6 % of the global ocean's surface area), with dissolution rates being a function of grain size, ambient seawater temperature, and pH.

Source: Lyman 2010 The reaction of the oceans to climate change are some of the most profound across the entire environment, including disruption of the ocean food chain through chemical changes caused by CO2, the ability of the sea to absorb CO2 being limited by temperature increases, (and the potential to expel sequestered CO2 back into the atmosphere as the water gets hotter), sea - level rise due to thermal expansion, and the amount of water vapour in the atmosphere.

Purely physical processes like wind - driven mixing can increase the uptake of CO2 by the oceans, but biological processes also play an important role, as does the temperature difference between the air and the water:

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

If as a result of physical processes (such as El Nino) warmer water reaches the surface of the ocean, so less heat is conducted from the atmosphere into the ocean and the atmopsheric temperature will therefore increase — on a much shorter — comparatively instantaneous — timescale.

Now since relative humidity remains roughly constant at the ocean surface and the air's capacity to hold water increases with temperature, relative humidity will actually decrease over land, particularly as one enters the continental interiors.

However the gradient of temperature in the ocean is maintained (roughly) as a balance between mixing from above and advection of cold water (from the poles) below.

Many of the surface currents of the world oceans (i.e., the ocean «gyres» which appear as rotating horizontal current systems in the upper ocean) are driven by the wind, however, the sinking in the Arctic is related to the buoyancy forcing (effects that change either the temperature or salinity of the water, and hence its buoyancy).
