Web10 de abr. de 2024 · Floating ice (b) displaces an equivalent mass of seawater, and so the melting of floating ice does not induce a mass change in the ocean, but it does produce a drop in salinity. This leads to a very small (generally negligible) GMSLR due to the reduction of seawater density and consequent increase in ocean volume (Noerdlinger & Brower, … WebAbstract: By applying engineering theory, we found that in order to achieve a certain degree of stem mechanical stability, trees with low wood dry‐mass density (ρD) need to produce thicker stems but invest less mass per unit stem length than those with high ρD. Mechanical stability was expressed as the ability of the vertical stem to either support a plant’s …
