The development of a neutrally buoyant groundline was undertaken to reduce the probability of large whale entanglements. The resulting product maintained a much lower profile in the water column compared to traditional groundlines[,] but in hard bottom areas it was susceptible to chaffing and breaking. In order to reduce mortalities once large whales are entangled, a weak rope was developed, again with the addition of barium sulphate. The breaking strength of this product was 1,065 pounds, ... half the weight of traditional groundlines. 2, record 1, English, - neutrally%20buoyant%20groundline

La mise au point d'une ligne de fond à flottabilité neutre a été entreprise en vue de réduire les risques d'enchevêtrement de grosses baleines. Le produit qui en résulte est maintenu bien plus bas dans la colonne d'eau par rapport aux lignes de fond traditionnelles, mais dans les zones au fond dur, il était vulnérable au frottement et à l'usure. Pour réduire les mortalités une fois que les grandes baleines sont prises dans les filets, on a mis au point un câble de faible résistance recouvert de sulfate de baryum. La résistance à la rupture de ce produit était de 1 065 livres, ce qui [...] correspond à la moitié du poids des lignes de fond traditionnelles. 2, record 1, French, - ligne%20de%20fond%20%C3%A0%20flottabilit%C3%A9%20neutre
